CyberRota Analysis
AI-GeneratedThe vulnerability affects rustls-webpki versions 0.101.0 through 0.103.11 and 0.104.0-alpha releases prior to 0.104.0-alpha.6, allowing X.509 name constraints for URI names to be ignored, which could lead to the acceptance of misissued certificates after successful signature verification. This flaw poses a low risk but should be prioritized by developers and organizations utilizing these specific versions of the library to ensure proper enforcement of certificate constraints and mitigate potential exploitation.

Original NVD Description
rustls-webpki (rustls/webpki) versions 0.101.0 through 0.103.11 and 0.104.0-alpha releases before 0.104.0-alpha.6 ignore X.509 name constraints that apply to URI names, causing such constraints to be accepted rather than enforced. Because name constraints are restrictions on otherwise properly issued certificates, the flaw is only reachable after successful signature verification and requires a misissued certificate to exploit; the library also provides no API for asserting URI names, and URI name constraints are otherwise unimplemented. Versions 0.103.12 and 0.104.0-alpha.6 reject URI name constraints unconditionally.
