Pre-auth out-of-bounds read via CID length underflow
Published Apr 24, 2026 · Updated Apr 24, 2026
Out-of-bounds read in Teluu PJPROJECT 2.16 and earlier allows remote attackers to read past a SIP multipart buffer via a malformed Content-ID URI. In cid_uri_to_hdr_value, a one-byte URI beginning with an angle bracket reaches a two-byte length subtraction before the patched minimum-length check. Applications processing incoming SIP multipart bodies with Content-ID headers expose this unauthenticated network path to unintended buffer reads.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
