CVE-2026-67543 - Heym Unsandboxed skill code execution: skills run via a local backend subprocess without the Docker isolation that Python tools mandate

CVE ID :CVE-2026-67543
Published : Nov. 11, 2026, 10:17 p.m. | 15 minutes ago
Description :Heym builds and runs agentic systems and business-process automations on self-hosted infrastructure. Prior to version 0.0.70, heym hardens one untrusted-code path but not its sibling. The Python tool executor (python_tool_executor.py) treats user code as untrusted and mandates a Docker sandbox (no network, read-only fs, non-root, no docker socket), failing closed. The skill executor (skill_python_executor.py) runs skill Python via a local backend subprocess with no Docker isolation — only a 512 MB RLIMIT and a 7-key env denylist — so a skill executes inside the backend execution context, with filesystem access, network egress, and non-denylisted environment variables that should not be exposed to untrusted/shared skills. In the shipped Docker config (backend runs as root + /var/run/docker.sock mounted), this escalates to host root. This issue has been patched in version 0.0.70.

CVE-2026-67544 - Heym: Playwright Custom Code Backend RCE via `playwrightCode` Field

CVE ID :CVE-2026-67544
Published : Nov. 11, 2026, 10:17 p.m. | 15 minutes ago
Description :Heym builds and runs agentic systems and business-process automations on self-hosted infrastructure. Prior to version 0.0.71, Heym's workflow engine accepts an arbitrary Python code string in the playwrightCode field of a Playwright node. This string is written to a temporary .py file and executed directly by the backend process via subprocess.Popen([sys.executable, script_path]) with no sandboxing, AST validation, or role gate. Any authenticated user — including a freshly registered account — can achieve full remote code execution (RCE) on the backend host, running as the service process user (observed as root in the default Docker deployment). This issue has been patched in version 0.0.71.

CVE-2026-67545 - Heym: Server-Side Request Forgery (SSRF) in HTTP Workflow Node

CVE ID :CVE-2026-67545
Published : Nov. 11, 2026, 10:17 p.m. | 15 minutes ago
Description :Heym builds and runs agentic systems and business-process automations on self-hosted infrastructure. Prior to version 0.0.73, the HTTP workflow node in Heym makes outbound HTTP requests to user-supplied URLs without validation of the target host or IP address. If a workflow author has already configured an HTTP node that targets internal addresses such as cloud metadata endpoints or private network hosts, and exposed the workflow with anonymous execution, an unauthenticated attacker can trigger the preconfigured SSRF sink. The same project has comprehensive SSRF protection in its MCP integration, which is absent from the HTTP node. This issue has been patched in version 0.0.73.

CVE-2026-67546 - Heym: Command execution via POST /api/mcp/fetch-tools stdio transport: supplied command is spawned before MCP validation

CVE ID :CVE-2026-67546
Published : Nov. 11, 2026, 10:17 p.m. | 15 minutes ago
Description :Heym builds and runs agentic systems and business-process automations on self-hosted infrastructure. Prior to version 0.0.75, the same POST /api/mcp/fetch-tools endpoint (any authenticated user, lowest role) also accepts the stdio transport, which spawns the attacker-supplied command with attacker-supplied args and an environment merged over os.environ. The process executes on the shared backend host before MCP protocol validation fails — so side effects fire regardless of whether the command speaks MCP. This is a distinct weakness class and exploit primitive from the SSRF (Advisory 2) on the same endpoint, and needs a different fix (role gating / opt-in trust boundary rather than egress controls). This issue has been patched in version 0.0.75.

CVE-2026-67547 - taOS: Authenticated Non-Admin Host Code Execution via Skill Runtime

CVE ID :CVE-2026-67547
Published : Nov. 11, 2026, 10:17 p.m. | 15 minutes ago
Description :taOS is a self-hosted AI agent OS. Prior to version 1.0.0-beta.23, the POST /api/skill-exec/{skill_id}/call endpoint in taOS executes built-in skills — including the code_exec skill which runs arbitrary Python via subprocess.run(["python3", "-c", code]) — without performing any admin role check, skill ownership check, or agent assignment verification. Any authenticated non-admin user can supply attacker-controlled Python code in the request body and have it executed as the taOS backend process user on the host, achieving full remote code execution with no privilege escalation required beyond a valid (non-admin) session. This issue has been patched in version 1.0.0-beta.23.

CVE-2026-67548 - taOS: Non-Admin Users Can Access System Settings and Update Actions

CVE ID :CVE-2026-67548
Published : Nov. 11, 2026, 10:17 p.m. | 15 minutes ago
Description :taOS is a self-hosted AI agent OS. Prior to version 1.0.0-beta.25, tinyagentos (taOS) registers all system settings routes under a single APIRouter() instance created with no admin authorization dependency. Any authenticated user—including non-admin invited users whose is_admin flag is explicitly False—can read the full system configuration, overwrite it, modify platform settings, trigger a git pull + dependency reinstall + service restart, and switch the tracked update branch. Successful exploitation of the write endpoints causes immediate configuration corruption or a denial of service for all users on the instance from a low-privileged account. This issue has been patched in version 1.0.0-beta.25.

CVE-2026-68511 - Paaster: TOCTOU race condition defeats the 'burn after reading' guarantee on view-once pastes

CVE ID :CVE-2026-68511
Published : Nov. 11, 2026, 10:17 p.m. | 15 minutes ago
Description :Paaster is a pastebin application. Prior to version 3.3.0, Paaster's "view once" (burn-after-reading) paste mode can be bypassed with concurrent requests. The check that's supposed to enforce single-use is a plain read followed by a separate write, with no atomicity, so multiple simultaneous requests can all see the paste as "not yet read" and all successfully retrieve it. This issue has been patched in version 3.3.0.

CVE-2026-68512 - Paaster: No rate limiting on account login, combined with a public username-enumeration/salt endpoint, enables offline credential-stuffing

CVE ID :CVE-2026-68512
Published : Nov. 11, 2026, 10:17 p.m. | 15 minutes ago
Description :Paaster is a pastebin application. Prior to version 3.3.0, Paaster's account login has no rate limiting, lockout, or CAPTCHA of any kind, and a companion endpoint openly discloses whether a username exists along with that account's password-hashing salts. Together these let an attacker enumerate real accounts and then brute-force their passwords with unlimited, unthrottled attempts. This issue has been patched in version 3.3.0.

CVE-2026-68538 - fulgur: Unbounded counters() expansion in generated content causes memory/CPU exhaustion (denial of service)

CVE ID :CVE-2026-68538
Published : Nov. 11, 2026, 10:17 p.m. | 15 minutes ago
Description :fulgur converts untrusted HTML/CSS into PDF, commonly on a server that processes input supplied by many tenants. From version 0.15.0 to before version 0.27.0, resolving the CSS counters(name, sep) function in generated content was bounded neither in the size of a single expansion nor in the aggregate work across an element tree. An attacker able to submit HTML/CSS to a fulgur-based conversion service can trigger CPU and memory exhaustion with a trivially small payload, denying service to the host and any co-tenants. This issue has been patched in version 0.27.0.

CVE-2026-68539 - fulgur: Unbounded string-set value accumulation causes memory/CPU exhaustion (denial of service)

CVE ID :CVE-2026-68539
Published : Nov. 11, 2026, 10:17 p.m. | 15 minutes ago
Description :fulgur converts untrusted HTML/CSS into PDF, commonly on a server that processes input supplied by many tenants. From version 0.4.4 to before version 0.29.0, the CSS string-set named-string values resolved from a document were accumulated per element with no memory budget, letting a small crafted document amplify into large retained memory (and the CPU to copy it) — results in a denial of service. This issue has been patched in version 0.29.0.

CVE-2026-81936 - Default OpenBMC Root Credential Reintroduced After Reset to Defaults in ThinkSystem v4 XCC3

CVE ID :CVE-2026-81936
Published : Nov. 11, 2026, 10:17 p.m. | 15 minutes ago
Description :An internal security review identified a development regression from ThinkSystem v4 XClarity Controller 3 (XCC3) versions (2.51) IHX432Y to (2.56) IHX436K which re-introduces the default OpenBMC root password upon performing an XCC Reset to Default operation.  An attacker can gain access to enabled administrative interfaces of XCC using the default OpenBMC credential re-introduced after Reset to Default. Additionally, this provides access to the underlying XCC Operating System which is not normally accessible. Only these versions are affected and are no longer available for download. Process enhancements have also been made to prevent and identify potential future regression.
