A request that percent-encodes a character of the path, inserts dot segments, or doubles a slash therefore reaches the protected resource under a URI that no rule regexp matches, and the vhost's default rule decides access. Deny rules, identity and group conditions, and unprotect and skip rules are bypassed alike.\n\nOnly a vhost whose default rule is more permissive than its other rules is affected. An authenticated user then reaches any URL a locationRules regexp was meant to restrict, but gains no more than that default rule already grants.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Vendor advisories\n\n- **Red Hat VEX** · updated 2026-09-25 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-95811.json)","depth":"twilight","depthScore":48,"depthScoreParts":{"impact":35.8,"likelihood":0.1,"exploitation":12,"ransomware":0},"changes":[{"seq":210856,"id":"CVE-2026-95811","ts":1790345445652,"field":"exploit_available","old":"false","new":"true"},{"seq":210855,"id":"CVE-2026-95811","ts":1790345445652,"field":"cvss","old":"5.4","new":"6.5"},{"seq":210649,"id":"CVE-2026-95811","ts":1790322139149,"field":"cvss","old":null,"new":"5.4"},{"seq":210648,"id":"CVE-2026-95811","ts":1790322139149,"field":"severity","old":"none","new":"medium"}]}
