🚨 CVE-2026-81714
openssl_encrypt (pip: openssl-encrypt) versions <= 1.4.8 use suffix-tolerant fingerprint matching in enroll_trust_key when binding a plugin-signing trust anchor. An operator who confirms a short (forgeable, ~32-bit) GPG key id could unknowingly enroll an attacker's colliding key as a trusted anchor, which then vouches for malicious plugins under the ENFORCE signature policy. Version 1.4.9 fixes this by requiring the confirmed value to exactly match the full primary-key fingerprint (case-insensitive, whitespace-stripped).

🚨 CVE-2026-81715
openssl_encrypt (pip package openssl-encrypt) versions <= 1.4.8 do not redact the keyserver bearer token passed as the positional argument to 'keyserver set-token' in the --debug argv dump, because sanitize_argv_for_debug fails to sanitize it. As a result the token is printed in cleartext to stderr under --debug (even without --unsafe-show-secrets), persisting the credential in logs and terminal history. Fixed in 1.4.9.

🚨 CVE-2026-81716
openssl_encrypt (pip: openssl-encrypt) versions before 1.4.9 contain a path traversal flaw in PluginSandbox._is_safe_path, which authorized file access using a bare string-prefix match. A sandboxed plugin without the READ_FILES permission could read or write another plugin's directory that merely shares a name prefix (e.g., .../plugins/foobar matching allowed .../plugins/foo), breaking per-plugin isolation within the same user. Fixed by matching each allowed directory exactly or with a trailing path separator.

🚨 CVE-2026-81717
openssl_encrypt (pip package openssl-encrypt) before 1.4.9 contains two weaknesses in the portable USB drive feature, whose threat model treats the removable drive as untrusted (attacker with physical write access). USBDriveCreator._verify_integrity_file only validates files listed in the manifest, so files added to the drive β€” including a root-level autorun payload β€” are not detected and integrity verification still passes. Additionally, a globally constant, source-embedded KDF salt (_LEGACY_FIXED_SALT) is used to derive the drive encryption key for any drive lacking a per-drive salt file, defeating precomputation resistance and enabling an offline rainbow-table attack.

🚨 CVE-2026-81718
openssl_encrypt versions before 1.4.9 use under-parameterized PBKDF2-HMAC-SHA256 with only 100,000 iterations to protect PQC keyfile private keys and 10,000 iterations for dual-encryption file-password verification. Attackers who obtain keyfiles or encrypted files can brute-force wrapping passwords offline using GPU or ASIC acceleration.

🚨 CVE-2026-81719
openssl_encrypt before 1.4.9 executes untrusted third-party plugins with insufficient controls: the plugin signature policy defaulted to WARN, so an unsigned/unverifiable non-built-in plugin was compiled and executed in the host process at import time, before the runtime sandbox is installed. The only default gate was an incomplete, bypassable AST denylist. If a user is induced to load an attacker's plugin, this results in arbitrary code execution with the privileges of the user running openssl_encrypt. Fixed in 1.4.9 by defaulting the signature policy to ENFORCE for non-built-in plugins.

🚨 CVE-2026-81720
openssl_encrypt before 1.4.9 fails to validate the memory_cost parameter from identity file protection blocks, allowing attackers to trigger out-of-memory conditions during key derivation. Attackers with write access to local identity stores can craft malicious identity files with excessive memory_cost values that cause the host to crash when unlocking identities before authentication.

🚨 CVE-2026-81721
openssl_encrypt before 1.4.9 fails to validate KDF cost parameters in encrypted file metadata and keystore headers, allowing attackers to trigger unbounded memory allocation. Attackers can craft malicious encrypted files declaring arbitrarily large Argon2, scrypt, or balloon KDF parameters to exhaust system memory and crash the process without authentication.

🚨 CVE-2026-81722
nltk PorterStemmer in versions <= 3.10.2 (fixed in 3.10.3) contains an inefficient-algorithmic-complexity denial of service in PorterStemmer.stem(). The _is_consonant() helper walks backward over the entire run of trailing 'y' characters on every call, and _measure() invokes it for each stem position, causing O(n^2) behavior. A single ~20-50 KB untrusted token consisting of a long run of the letter 'y' followed by a matching suffix (e.g., 'ness') can pin a CPU core for seconds to minutes, causing availability impact.

🚨 CVE-2026-81723
NLTK versions before 3.10.3 contain a quadratic CPU exhaustion vulnerability in XMLCorpusView._read_xml_fragment() that rescans accumulated XML fragments on every 1 KiB block read. Attackers can provide malformed XML corpus files to cause severe CPU consumption and denial of service through affected readers like BNCCorpusReader.

🚨 CVE-2026-81725
NLTK before 3.10.3 contains a regular expression denial of service vulnerability in Pl196xCorpusReader that allows attackers to cause quadratic CPU consumption by supplying malformed TEI blocks with many unmatched opening tags. Attackers can exploit lazy regex patterns in the read_block method through public APIs like words() and tagged_words() to force repeated rescans and achieve near-quadratic runtime growth.

🚨 CVE-2026-81726
NLTK through 3.10.3 contains a path traversal vulnerability in model-artifact APIs that bypass pathsec enforcement by using raw file operations on caller-controlled paths. Attackers can read or write files outside allowed sandbox roots through TransitionParser, AveragedPerceptron, PerceptronTagger, and maxent parameter APIs when pathsec is enabled.

🚨 CVE-2026-81727
NLTK versions before 3.10.3 contain a filesystem containment bypass vulnerability in the Downloader.download and Downloader.incr_download methods that allows attackers to overwrite files outside the install root through pre-existing hardlinks. Attackers with write access to a shared downloader directory can create hardlinks pointing to outside-root files that are then overwritten during normal package extraction, mutating files outside the intended install tree.

🚨 CVE-2026-81735
startServer.ts in the mcp-http-server package of UI-TARS-desktop defaulted its listen address to '::' when no host was given, so startSseAndStreamableHttpMcpServer bound the Streamable HTTP and SSE MCP transports to every interface, and its authentication middleware was optional: middlewares are applied only when a caller supplies them. The @agent-infra/mcp-server-commands and @agent-infra/mcp-server-filesystem entry points call startSseAndStreamableHttpMcpServer with a host and port alone and pass no middleware, so neither server required a credential. The commands server exposes a run_command tool that hands its caller-supplied command string to promisify(child_process.exec), so any unauthenticated client able to reach the port could run arbitrary commands as the user running the server, and the filesystem server exposed its file read and write tools on the same terms. The listen default became 127.0.0.1 in commit c2ad42e3eb9b27830db41a3e6f51ca7179d9b168; the package version stayed at 1.2.4 across that change, so the boundary is the commit rather than a release.

🚨 CVE-2026-81817
Affected versions of Flowintel contain an insecure direct object reference / broken object-level authorization issue across numerous task endpoints.


The routes generally received both a case identifier and a task identifier, but previously they did not enforce that the task actually belonged to the supplied case. As a result, an authenticated user with editor-level access to one case could potentially substitute the ID of a task from another case and invoke operations against that foreign task.


The patch introduces task_case_bound_required, which loads both objects and returns 404 unless the task belongs to the requested case. This protection is applied to edit, delete, note, assignment, status, file, export, MISP-linking, subtask, external-reference, and other task-related endpoints.

The fix also adds explicit checks that a requested note_id belongs to the current task before returning or exporting it, closing related cross-object access paths.

Version impacted =>3.3.0

🚨 CVE-2026-81818
Affected versions of Flowintel contain an authorization flaw in the administrative user-edit API.


The existing authorization check correctly prevented an organization administrator from editing users in another organization, but it did not prevent them from editing a full administrator within their own organization. As a result, an org admin could modify that full administrator account, including changing its password. The upstream commit explicitly describes the issue as:


β€œOrg admin can change the password of a full admin in the same organization.”


The fix adds a higher-privilege boundary check:


if user_to_edit.is_admin(): return ... 403

so organization administrators can no longer modify full administrator accounts.

Version impacted >=3.3.0

🚨 CVE-2026-81819
Affected versions of Flowintel expose the /my_assignment/user API endpoint to any authenticated API user. The endpoint accepts a user_id parameter identifying the user whose assignments should be returned, but previously had no role restriction beyond general API authentication.


As a result, a lower-privileged authenticated user could potentially query another user’s assignment information by supplying that user’s identifier.


The fix changes:


method_decorators = [api_required]


to:


method_decorators = [admin_or_org_admin_required, api_required]

so only administrators or organization administrators can perform cross-user assignment queries.

Version impacted =>3.3.0

🚨 CVE-2026-81820
Affected versions of Flowintel construct timeline HTML using attacker-controllable MISP object fields such as:



*
object UUID;


*
object name;


*
attribute value;


*
attribute type;


*
comment;


*
first/last seen values;


*
IDS flag.





Those values were concatenated directly into HTML strings before rendering. The upstream commit explicitly states that DOMPurify removed XSS vectors but still allowed other HTML elements, such as forms, through.

The fix replaces direct string interpolation with DOM construction via document.createElement() and assigns all attacker-controlled values using textContent. The headline is similarly converted to escaped HTML through a temporary element.

Version impacted =>3.3.0

🚨 CVE-2026-81826
Affected versions of Flowintel do not revoke existing authenticated sessions when a user’s password is changed.


This means that if an attacker already possesses a valid sessionβ€”for example, from prior access or a stolen session tokenβ€”the victim changing their password does not terminate that attacker’s access. The session remains usable until it expires naturally. The upstream commit describes this directly as:


β€œsession keeps working until it expires.”

The fix detects password changes and explicitly invokes _invalidate_user_sessions(user.id) after the database update. This is applied in both edit_user_core() and admin_edit_user_core().

Version impacted >=3.3.0

🚨 CVE-2026-81827
Affected versions of Flowintel incorrectly attempted to validate login email addresses by calling Email(email). That does not perform WTForms field validation; it merely constructs a validator object.


Consequently, malformed attacker-controlled email input could continue through the login process and be written to security-relevant logs. The vulnerable code inserted the supplied email into both a warning log and the custom audit logger. Since CR/LF characters were not escaped, an unauthenticated attacker could potentially inject additional physical log lines or forge misleading log entries.

The patch corrects the validation call to Email()(form, form.email), changes the standard logging call to parameterized logging, and introduces _sanitize_log_fragment() so carriage returns and line feeds are encoded instead of creating new records.

Version impacted >=3.3.0
