CVE-2026-11718 - Google Cloud Token Validation Authentication Bypass

CVE ID :CVE-2026-11718
Published : June 18, 2026, 11:52 a.m. | 2 hours, 16 minutes ago
Description :An authentication bypass vulnerability exists in the generic opaque token validation path (validateOpaqueToken) of googleapis/mcp-toolbox. When the toolbox validates an opaque token via an OAuth 2.0 introspection endpoint (RFC 7662), it decodes the response into an introspectResp struct. However, the subsequent claim-checking logic (validateClaims) evaluates the issuer condition as if a.issuer != "" && iss != "". If the external OAuth provider's introspection response omits the optional iss (issuer) field completely, the variable iss defaults to an empty string. This causes the conditional block to evaluate to false and be skipped silently. Consequently, the application accepts tokens issued by unauthorized or unintended third-party identity providers.

CVE-2026-11719 - MCP Toolbox for Databases Authorization Bypass

CVE ID :CVE-2026-11719
Published : June 18, 2026, 11:55 a.m. | 2 hours, 14 minutes ago
Description :An authenticated authorization bypass vulnerability exists in MCP Toolbox for Databases due to missing scope enforcement across older protocol handlers. While the 2025-11-25 protocol version handler correctly enforces per-tool restrictions defined by scopesRequired, older supported protocol versions (2025-06-18, 2025-03-26, and 2024-11-05) omit this check. An authenticated client with low-privilege tokens (e.g., read) can bypass the intended per-tool scope restrictions and execute high-privilege tools (e.g., admin) simply by specifying an older protocol version in the MCP-Protocol-Version header, or by omitting the header entirely (which causes the server to default to the vulnerable 2024-11-05 handler).

CVE-2026-54219 - Stored XSS in UBB.threads

CVE ID :CVE-2026-54219
Published : June 18, 2026, 12:56 p.m. | 1 hour, 12 minutes ago
Description :UBB.threads is vulnerable to Stored XSS via user posts and user profile fields. The application fails to properly sanitize user input, allowing low privileged attackers to inject arbitrary JavaScript that executes in a victim's browser upon viewing. Because vendor contact attempts were unsuccessful, the vulnerability has only been confirmed in version 7.7.5 but may also affect other versions.

CVE-2026-54222 - Blind SQL Injection in UBB.threads

CVE ID :CVE-2026-54222
Published : June 18, 2026, 12:56 p.m. | 1 hour, 12 minutes ago
Description :UBB.threads is vulnerable to Blind SQL Injection, allowing attackers with access to the Members in Control Panel to interact with the underlying database. Due to insufficient input sanitization, an attacker can extract sensitive information, such as user credentials, by manipulating SQL queries through time-based or boolean-based techniques. Because vendor contact attempts were unsuccessful, the vulnerability has only been confirmed in version 7.7.5 but may also affect other versions.

CVE-2026-54224 - Denial of Service in UBB.threads

CVE ID :CVE-2026-54224
Published : June 18, 2026, 12:56 p.m. | 1 hour, 12 minutes ago
Description :UBB.threads is vulnerable to Denial of Service (DoS). By sending multiple concurrent requests to view any user profile on instances with many registered users, an authenticated attacker can easily exhaust database resources and completely deny access to the application for other users. Because vendor contact attempts were unsuccessful, the vulnerability has only been confirmed in version 7.7.5 but may also affect other versions.

CVE-2026-55205 - Hermes WebUI < 0.51.468 - Resource Exhaustion via Unauthenticated OAuth Flow Endpoint

CVE ID :CVE-2026-55205
Published : June 18, 2026, 3:49 p.m. | 2 hours, 21 minutes ago
Description :Hermes WebUI before 0.51.468 contains a resource exhaustion vulnerability in the unauthenticated POST /api/onboarding/oauth/start endpoint that allows unbounded accumulation of in-memory flow state and daemon threads. Attackers can send repeated or concurrent requests to exhaust server memory and thread resources, potentially triggering repeated outbound device-code requests to upstream OAuth providers.

CVE-2026-55203 - HAProxy - Integer Overflow in FCGI Demux Record Length Field

CVE ID :CVE-2026-55203
Published : June 18, 2026, 4:05 p.m. | 2 hours, 4 minutes ago
Description :HAProxy through 3.4.0, fixed in commit 5985276, contains an integer overflow vulnerability in the fcgi_conn structure's drl field that allows buffer misparse as new FCGI record headers. When contentLength is 65535 and paddingLength is 1 or more, the drl field wraps to 0, causing incorrect record consumption and allowing malicious FastCGI backends to desynchronize the FCGI framing parser, potentially causing request routing errors, response smuggling, or memory safety issues.

Published : June 18, 2026, 4:05 p.m. | 2 hours, 4 minutes ago
Description :HAProxy through 3.4.0, fixed in commit 9a6d1fe, contains a null pointer dereference vulnerability in hpack_dht_insert() within src/hpack-tbl.c that fails to validate the return value of hpack_dht_defrag() when the memory pool is exhausted. An attacker can trigger HPACK dynamic table insertions under memory pressure to dereference a NULL pointer and crash HAProxy worker processes, causing denial of service.

CVE-2025-32392 - AutoGPT has a DoS vulnerability in LoopVideoBlock

CVE ID :CVE-2025-32392
Published : June 18, 2026, 4:08 p.m. | 2 hours, 1 minute ago
Description :AutoGPT is a workflow automation platform for creating, deploying, and managing continuous artificial intelligence agents. Prior to 0.6.63, AutoGPT's LoopVideoBLock allows users to input a video file and process the video, such as looping it 5 times or extending the time, and finally writing it to disk. However, there is no limit on the resources that can be allocated during execution. For example, the number of loops is user-controllable and unlimited. When a malicious attacker loops too many times, the generated video is too large, and after writing it to disk, the disk space is exhausted, eventually causing DoS. Version 0.6.63 patches the issue.

CVE-2026-54103 - U.S. GAO EPDS and CBCA EDS unauthenticated password change

CVE ID :CVE-2026-54103
Published : June 18, 2026, 4:12 p.m. | 1 hour, 57 minutes ago
Description :The U.S. Government Accountability Office (GAO) Electronic Protest Docketing System (EPDS) and Civilian Board of Contract Appeals (CBCA) Electronic Docketing System (EDS) does not authenticate password change requests to the '/update-profile/N' API endpoint. A remote, unauthenticated attacker could change an arbitrary user's password.

CVE-2025-32422 - AutoGPT has a DoS vulnerability in FileStoreBlock with StepThroughItemsBlock

CVE ID :CVE-2025-32422
Published : June 18, 2026, 4:12 p.m. | 1 hour, 57 minutes ago
Description :AutoGPT is a workflow automation platform for creating, deploying, and managing continuous artificial intelligence agents. Prior to 0.6.63, `StepThroughItemsBlock` can iterate all the contents in a list and send them to `FileStoreBlock` for downloading one by one. Although `FileStoreBlock` has access time limits for downloading files, `StepThroughItemsBlock` can be used to slowly iterate and download relatively small files (e.g., 100M) multiple times. `StepThroughItemsBlock` does not limit the number of loops. In addition, `FileStoreBlock` does not limit the amount of disk space consumed in the current working directory. When a malicious user chooses to download too many videos, the disk space will eventually run out, causing a DoS. Version 0.6.63 patches the issue.

Description :The U.S. Government Accountability Office (GAO) Electronic Protest Docketing System (EPDS) and Civilian Board of Contract Appeals (CBCA) Electronic Docketing System (EDS) expose sensitive account information through the 'update-profile/' API endpoint. A remote, unauthenticated attacker can submit a request containing an arbitrary 'user_id' parameter and receive a JSON response containing account-specific information, including the associated email address.
