CVE-2026-40944

6.9 mediumEPSS 0.2%

Medium (6.9). EPSS 0.2% chance of exploitation in the next 30 days. Fixed in github.com/oxia-db/oxia 0.16.2.

Oxia is a metadata store and coordination system. Prior to 0.16.2, the trustedCertPool() function in the TLS configuration only parses the first PEM block from CA certificate files. When a CA bundle contains multiple certificates (e.g., intermediate + root CA), only the first certificate is loaded. This silently breaks certificate chain validation for mTLS. This vulnerability is fixed in 0.16.2.
