Multiple parsing functions in the affected library do not validate whether their input values are nil before attempting to access elements, which can lead to a panic (index out of range). Panics during the parsing of a configuration file may introduce ambiguity and vulnerabilities, hindering the correct interpretation and configuration of the web server.","published":"2024-02-17T05:15:08.747","modified":"2026-06-17T07:09:36.567","cvss":{"score":5.3,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[],"fix":null,"references":[{"type":"ADVISORY","url":"https://blog.trailofbits.com/2023/09/18/security-flaws-in-an-sso-plugin-for-caddy/"},{"type":"REPORT","url":"https://github.com/greenpau/caddy-security/issues/263"},{"type":"ADVISORY","url":"https://security.snyk.io/vuln/SNYK-GOLANG-GITHUBCOMGREENPAUCADDYSECURITY-5961078"},{"type":"ADVISORY","url":"https://blog.trailofbits.com/2023/09/18/security-flaws-in-an-sso-plugin-for-caddy/"},{"type":"REPORT","url":"https://github.com/greenpau/caddy-security/issues/263"},{"type":"ADVISORY","url":"https://security.snyk.io/vuln/SNYK-GOLANG-GITHUBCOMGREENPAUCADDYSECURITY-5961078"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-06-17T07:09:36.567"}}
