Detailsinfo

A vulnerability, which was classified as problematic, was found in oxia-db oxia up to 0.16.1. Affected is the function trustedCertPool of the component Certificate Chain Handler. The manipulation with an unknown input leads to a certificate validation vulnerability. CWE is classifying the issue as CWE-295. The product does not validate, or incorrectly validates, a certificate. This is going to have an impact on integrity. CVE summarizes:

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.

The advisory is available at github.com. This vulnerability is traded as CVE-2026-40944 since 04/15/2026. The exploitability is told to be difficult. It is possible to launch the attack remotely.
