Prior to versions 5.4.54, 6.4.46, 7.4.19, and 8.1.7, HeaderUtils::split() parsed header values with a pattern whose token alternative also matched whitespace, followed by a (?<!\\s) lookbehind. A run of whitespace placed before a separator could be divided among the iterations of the enclosing repetition in exponentially many ways, and the engine tried all of them before settling. HeaderBag calls it for the Cache-Control header whenever a Request is built, so any application handling HTTP requests is reachable, with no authentication.\nA single request carrying such a header costs close to a second of CPU (813 ms for a run of 17 spaces in an 8 KB header on PHP 8.5, doubling with each extra space). From 18 spaces on, preg_match_all() gives up at pcre.backtrack_limit and split() returns an empty array, so every directive of the header is silently dropped.\nThis issue affects symfony/http-foundation v4.1.0-BETA1 prior to v5.4.54, v6.0.0-BETA1 prior to v6.4.46, v7.0.0-BETA1 prior to v7.4.19, and v8.0.0-BETA1 prior to v8.1.7.\nhttps://www.cve.org/CVERecord?id=CVE-2026-108082https://github.com/symfony/symfony/pull/66048https://github.com/symfony/symfony/pull/66491https://github.com/symfony/symfony/security/advisories/GHSA-r925-mgvr-h9cchttps://symfony.com/blog/cve-2026-108082-redos-in-headerutils-split-reachable-through-the-cache-control-request-header#symfony #sensiolabs#CVE_2026_108082#bot", "url": "https://infosec.exchange/users/cve/statuses/117445510012550626"}, {"timestamp": "2026-10-15T15:17:22.583Z", "date_only": false, "value": "2026-10-15T15:17:22.583", "kind": "milestone", "label": "Published", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-108082", "record": "FKIE_CVE-2026-108082", "field": "published"}, {"timestamp": "2026-10-15T15:32:05.788Z", "date_only": false, "value": "2026-10-15T15:32:05.788Z", "kind": "other", "label": "Updated", "source": "cvelistv5 / Checkmarx", "record": "CVE-2026-108082", "field": "containers.cna.providerMetadata.dateUpdated"}, {"timestamp": "2026-10-15T18:04:09.776Z", "date_only": false, "value": "2026-10-15T18:04:09.776300Z", "kind": "other", "label": "Recorded", "source": "cvelistv5 / CISA-ADP", "record": "CVE-2026-108082", "field": "containers.adp.0.metrics.0.other.content.timestamp"}, {"timestamp": "2026-10-15T18:04:09.776Z", "date_only": false, "value": "2026-10-15T18:04:09.776300Z", "kind": "other", "label": "Recorded", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-108082", "record": "FKIE_CVE-2026-108082", "field": "metrics.ssvcV203.0.ssvcData.timestamp"}, {"timestamp": "2026-10-15T18:04:45.913Z", "date_only": false, "value": "2026-10-15T18:04:45.913Z", "kind": "other", "label": "Updated", "source": "cvelistv5", "record": "CVE-2026-108082", "field": "cveMetadata.dateUpdated"}, {"timestamp": "2026-10-15T18:04:45.913Z", "date_only": false, "value": "2026-10-15T18:04:45.913Z", "kind": "other", "label": "Updated", "source": "cvelistv5 / CISA-ADP", "record": "CVE-2026-108082", "field": "containers.adp.0.providerMetadata.dateUpdated"}, {"timestamp": "2026-10-16T00:00:00Z", "date_only": false, "value": "2026-10-16T00:00:00Z", "kind": "milestone", "label": "Published", "source": "osv_ubuntu \u00b7 UBUNTU-CVE-2026-108082", "record": "UBUNTU-CVE-2026-108082", "field": "published"}, {"timestamp": "2026-10-16T00:00:00Z", "date_only": false, "value": "2026-10-16T00:00:00Z", "kind": "other", "label": "Updated", "source": "osv_ubuntu \u00b7 UBUNTU-CVE-2026-108082", "record": "UBUNTU-CVE-2026-108082", "field": "modified"}, {"timestamp": "2026-10-16T16:00:33.533Z", "date_only": false, "value": "2026-10-16T16:00:33.533", "kind": "other", "label": "Updated", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-108082", "record": "FKIE_CVE-2026-108082", "field": "lastModified"}, {"timestamp": "2026-10-17T01:39:32.015Z", "date_only": false, "value": "2026-10-17T01:39:32.015713Z", "kind": "sighting", "label": "Seen", "source": "https://bsky.app/profile/r-netsec.bsky.social/post/3mxzxh4mj5o2y", "record": "CVE-2026-108082", "field": "creation_timestamp", "uuid": "06dc3dec-796f-4805-aa0b-f534e73c27a7", "content": "CVE-2026-108082: Symfony ReDoS.
