The sibling HTTP::Session::Store::Memcached rejects ids that contain control characters, but the CHI store has no such check, and CHI does not escape keys for its memcached drivers.\n\nWith a memcached driver, a CR and LF in the session id end the cache command early, and the server reads the bytes after them as further commands.","cvss_v4":null,"cvss_v3":null,"cwes":["CWE-93"],"references":["https://github.com/tokuhirom/http-session/commit/58288cbf941da6d2aad4ff5c0c79e523d9e583b4.patch","https://metacpan.org/release/KTAT/http-session-0.53/source/lib/HTTP/Session/Store/CHI.pm","https://metacpan.org/release/TOKUHIROM/http-session-0.54/changes","http://www.openwall.com/lists/oss-security/2026/11/01/2"],"reference_tags":[{"url":"https://github.com/tokuhirom/http-session/commit/58288cbf941da6d2aad4ff5c0c79e523d9e583b4.patch","tags":[]},{"url":"https://metacpan.org/release/KTAT/http-session-0.53/source/lib/HTTP/Session/Store/CHI.pm","tags":[]},{"url":"https://metacpan.org/release/TOKUHIROM/http-session-0.54/changes","tags":[]},{"url":"http://www.openwall.com/lists/oss-security/2026/11/01/2","tags":[]}],"products":[],"affected":[],"source":"nvd","synced_at":"2026-11-01T20:41:13.136840013+00:00"},"epss":null,"kev":null,"exploits":[],"weaknesses":[{"name":"Improper Neutralization of CRLF Sequences","common_name":"CRLF Injection","deprecated":false,"replaced_by":[],"id":"CWE-93"}],"osv":[],"fixed":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
