Several of these patterns place unbounded quantifiers next to each other before a trailing `\\s*$` anchor. A valid date prefix followed by a long interior run of digits, letters, or whitespace and a single trailing byte that defeats the final match forces the engine to repartition the run, giving polynomial (about quadratic) backtracking. A header value of a few tens of kilobytes runs for tens of seconds of CPU.\n\nHTTP::Date parses timestamps such as HTTP `Date`, `Expires`, and `Last-Modified` headers, which commonly originate from untrusted sources. Any caller that passes an untrusted date header to str2time() or parse_date() can be driven to consume unbounded CPU, a denial of service."}],"problemTypes":[{"descriptions":[{"cweId":"CWE-1333","description":"CWE-1333 Inefficient Regular Expression Complexity","lang":"en","type":"CWE"}]}],"providerMetadata":{"orgId":"9b29abf9-4ab0-4765-b253-1875cd9b441e","shortName":"CPANSec","dateUpdated":"2026-07-17T15:20:07.201Z"},"references":[{"tags":["patch"],"url":"https://github.com/libwww-perl/HTTP-Date/commit/78c20952cdfbf11e03cf1199ad70f13298a84c5c.patch"},{"tags":["issue-tracking"],"url":"https://github.com/libwww-perl/HTTP-Date/pull/33"},{"tags":["release-notes"],"url":"https://metacpan.org/release/OALDERS/HTTP-Date-6.08/changes"}],"solutions":[{"lang":"en","value":"Upgrade to HTTP::Date 6.08 or later, which rejects input longer than 64 characters before the date-parsing regexes run."}],"source":{"discovery":"UNKNOWN"},"timeline":[{"lang":"en","time":"2026-07-09T00:00:00.000Z","value":"Version 6.08 released with the fix."}],"title":"HTTP::Date versions before 6.08 for Perl allow CPU exhaustion via polynomial regex backtracking in parse_date","x_generator":{"engine":"cpansec-cna-tool 0.1"}},"adp":[{"metrics":[{"cvssV3_1":{"scope":"UNCHANGED","version":"3.1","baseScore":7.5,"attackVector":"NETWORK","baseSeverity":"HIGH","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","integrityImpact":"NONE","userInteraction":"NONE","attackComplexity":"LOW","availabilityImpact":"HIGH","privilegesRequired":"NONE","confidentialityImpact":"NONE"}},{"other":{"type":"ssvc","content":{"timestamp":"2026-08-12T18:47:05.416355Z","id":"CVE-2026-14741","options":[{"Exploitation":"none"},{"Automatable":"yes"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-08-12T18:47:08.460Z"}},{"title":"CVE Program Container","references":[{"url":"http://www.openwall.com/lists/oss-security/2026/07/17/10"}],"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2026-07-17T17:25:13.175Z"}}]}}
