{"id":"CVE-2026-107885","published":"2026-10-09T04:18:04.940","lastModified":"2026-10-09T21:17:03.713","description":"OpenPrinting CUPS through 2.4.20 contains a resource-exhaustion vulnerability in the submission-timeout handling of cupsdCheckJobs(). The scheduler suppresses timeout processing for all pending jobs whenever any client connection has an in-flight Send-Document operation, without matching that connection to the job being examined. A client allowed to reach the IPP service can hold an incomplete HTTP request containing parsed Send-Document headers before operation authorization, preventing unrelated incomplete jobs from expiring. Where Create-Job submission is allowed, incomplete jobs can accumulate until MaxJobs is exhausted and further legitimate print submissions are rejected. The suppression ends when the held connection closes.","cvssScore":3.3,"cvssSeverity":"LOW","cvssVector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L","cwes":["CWE-770"],"vendors":[],"products":[],"references":[{"url":"https://github.com/OpenPrinting/cups/security/advisories/GHSA-hhw5-qqmc-p6rg","tags":[]},{"url":"https://github.com/OpenPrinting/cups/security/advisories/GHSA-hhw5-qqmc-p6rg","tags":[]}],"exploitRefs":[{"url":"https://github.com/OpenPrinting/cups/security/advisories/GHSA-hhw5-qqmc-p6rg","tags":[]},{"url":"https://github.com/OpenPrinting/cups/security/advisories/GHSA-hhw5-qqmc-p6rg","tags":[]}],"hasPoc":true,"ai":null}
