Technical description

The AsyncHttpClient (AHC) library allows Java applications to easily execute HTTP requests and asynchronously process HTTP responses. Prior to 3.0.13 and 2.16.1, cross-host request replay updates the current request but leaves the target request and related proxy context pointing at the original origin. Connection-pool selection, CONNECT handling, realm selection, and TLS setup can consequently send the original host's path, Host header, Authorization credentials, or plaintext request to the replay destination. Documented ResponseFilter failover and retry paths can trigger the replay. This issue is fixed in versions 3.0.13 and 2.16.1.

———mcp-from-openapi from 2.5.0 before 2.9.0 contains a credential exposure vulnerability that allows attackers to capture Authorization and Cookie headers because safeFetch() forwards them on cross-origin redirects. Attackers controlling a spec host or abusing an open redirect can redirect fromURL() spec requests to their own origin to steal bearer tokens or cookies.6h CVE-2026-1115948.1 HIG

——4Incus 6.0.3 before 6.0.7, 6.6.0 before 7.0.2, and 7.1.0 before 7.5.0 contains an improper authorization vulnerability that allows restricted TLS clients to read storage bucket keys in the default project. Attackers can query the bucket keys endpoints to obtain S3 access and secret keys, then read, modify or delete objects in those buckets.2h CVE-2026-1146129.9 CRI

——4LiteLLM is a proxy server (AI Gateway) to call LLM APIs in OpenAI (or native) format. From 1.87.0 until 1.100.4, 1.101.3, 1.102.2, 1.103.1, and 1.104.0-rc.2, the proxy reuses one cryptographic context for at-rest secrets and session tokens, allowing an authenticated internal user to have crafted metadata containing a forged administrator credential encrypted and returned by the API-key flow. Replaying that ciphertext as a bearer token causes the proxy to trust the forged proxy administrator identity, permitting administrative access and arbitrary commands through the MCP stdio endpoint. Versions 1.87.0 through 1.90.x require EXPERIMENTAL_UI_LOGIN to be enabled, while versions after 1.91.0 are exploitable in the default configuration. This issue was fixed in LiteLLM 1.100.4, 1.101.3, 1.102.2, 1.103.1, and 1.104.0-rc.2.1d CVE-2026-218122.2 LOW

——2HCL AppScan Azure Boards Plugin is potentially affected by an Information Disclosure vulnerability involving secrets accessible in plaintext during pipeline execution. Depending on the pipeline configuration, these secrets could be exposed through task outputs, debug logs, environment variable dumps, or build agent scripts, despite being masked in the user interface.1d
