CVE-2024-56731

Executive Summary (TL;DR)

Gogs tried to stop hackers from deleting `.git` files by checking file names. Hackers bypassed this by using symbolic links (e.g., `evil_link` -> `.git/config`). By editing the symlink via the Web UI, attackers can overwrite Git hooks and achieve full RCE. CVSS 10.0.

A critical Remote Command Execution vulnerability in Gogs versions prior to 0.13.3. This flaw is a bypass of a previous fix (CVE-2024-39931), allowing authenticated users to overwrite internal Git files via symbolic links.

GHSA-7PPR-R889-MCF2: Unbounded WebSocket Message Aggregation in http4s-blaze-server leads to Denial of Service

An uncontrolled resource consumption vulnerability exists in the Scala-based http4s-blaze-server package of the http4s/blaze library. The vulnerability allows remote, unauthenticated attackers to cause an Out of Memory Error (OOM) and JVM crash by streaming a continuous sequence of small or empty WebSocket continuation frames with the FIN bit set to 0. This bypasses typical payload size checks because of the JVM's per-object allocation overhead, leading to rapid heap exhaustion with minimal network bandwidth.

GHSA-95cv-r8x4-vh75: Path Traversal Vulnerability in OpenList Batch Rename Handler

A critical path traversal vulnerability has been identified in the OpenList Go-based backend package. The vulnerability exists within the batch rename handler because the application does not validate the source filename parameter before constructing filesystems paths. This omission allows authenticated users to escape their designated directory and rename files in sibling paths.

GHSA-P6PH-3JX2-3337: Horizontal Privilege Escalation and Metadata Information Disclosure via Bleve Search in OpenList

OpenList version 4.2.3 and prior is vulnerable to an authorization bypass and metadata leakage. When configured with the Bleve search engine backend, OpenList fails to perform separator-aware path matching when validating tenant containment. This allows authenticated users to access sibling directories sharing similar name prefixes. Furthermore, the search backend returns unfiltered global result counts, leaking existence verification data of unauthorized files via side-channel analysis.

GHSA-86cx-wwf4-phq4: Path Prefix Confusion Authorization Bypass in OpenList

An authorization bypass vulnerability in OpenList version 4.2.3 and below allows authenticated users to read arbitrary files outside of their designated base directories due to an insecure path prefix check using Go's standard strings.HasPrefix function.

CVE-2026-16584: Security Policy Bypass in AWS API MCP Server via Startup Initialization Failure

A security policy bypass vulnerability exists in the AWS API MCP Server (awslabs-aws-api-mcp-server) from version 0.2.13 through 1.3.46. When the server fails to load the read-only operations index during startup (due to transient network failures, file permission issues, or other exceptions), it logs a warning but continues running in an insecure, degraded state. Under this condition, the security policy engine fails open, silently skipping all subsequent security checks and consent prompts for the lifetime of the process. This permits unauthorized mutating AWS CLI commands to execute via indirect prompt injection attacks.
