CVE-2026-40944 Details
Description
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.
A vulnerability in Oxia versions prior to 0.16.2 allows the TLS configuration's trustedCertPool() function to improperly handle CA certificate files containing multiple certificates. Only the first certificate in the PEM bundle is loaded, which can disrupt certificate chain validation for mutual TLS (mTLS) deployments. This issue arises because the trustedCertPool() method only processes a single PEM block, discarding any additional certificates without error, leading to a broken validation chain for mTLS.
Users can upgrade to Oxia version 0.16.2 or later to address this vulnerability. Alternatively, for versions prior to 0.16.2, CA files can be used that contain only a single certificate, specifically the direct issuer of client certificates, rather than a chain.
