Security-decision bypass via omitted absolutePath comparison
Published May 8, 2026 · Updated May 8, 2026
Incorrect URI comparison in uriparser before 1.0.2 allows attackers to make distinct scheme-only URIs compare as equal. The EqualsUri family in src/UriCompare.c omits the absolutePath flag when comparing hostless URIs, so scheme:/path1 and scheme:path1 receive the same result. Exploitation requires a consuming application to compare an attacker-influenced URI and trust equality for a security decision, which can redirect that decision to a different URI identity.

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.
