PYSEC-2026-3809 asyncssh has an incomplete fix for CVE-2026-45309 — AuthorizedKeysFile %u still escapes the intended directory via a leading ~ (and weakly via ${ENV}) username substitution

Incomplete fix for CVE-2026-45309 GHSA-g794-3fmp-753h. The 2.23.0 guard that sanitises the SSH username before %u substitution in AuthorizedKeysFile blocks /, \ and .., but does not block a leading or $ENV, both of which are re-introduced by later expansion and reach the file open — defeating the...

senaite.core Vulnerable to Eval Injection and Missing Authorization

SummaryAn unauthenticated remote code execution vulnerability in the SENAITE JSON API allows any network-reachable attacker to execute arbitrary Python on the Zope worker process via a two-request anonymous chain. The /@@API/update route is reachable to anonymous callers and runs eval on...

reachy_mini Allows Unrestricted Upload of File with Dangerous Type

SummaryThe Reachy Mini daemon exposes the “/api/media/sounds/upload” endpoint without authentication and file validation mechanisms. An attacker can use this endpoint to upload malicious files into the file system that will propagate in future attacks. Compromise Chain: Unauthenticated to Full Ro...

qwed Vulnerable to Authenticated Remote Code Execution via Unsafe SymPy `parse_expr()`

SummaryThe qwed package version 5.1.1 passes attacker-controlled input directly to SymPy's parseexpr function without a restricted namespace. Because parseexpr internally calls Python's eval, any authenticated tenant can execute arbitrary Python code inside the API server process. The attack...

PraisonAI: `--api-key` flag on `praisonai serve` is not properly enforced

Summarypraisonai serve agents and praisonai serve unified both accept --api-key for authentication. The flag is parsed but never wired into the FastAPI app — no middleware, no header check, nothing. The server runs wide open regardless of what key you set. Tested on 4.6.50 from PyPI. Affected...

PraisonAI serve agents --api-key is ignored, allowing unauthenticated remote agent execution

Summary PraisonAI's praisonai serve agents command exposes --api-key as the documented authentication control for production/external deployments, but the configured key is not enforced on the public agent invocation compatibility endpoints. An operator can start the server with --api-key and bin...
