{"cve":"CVE-2026-85062","nvd":{"published":"2026-09-03T21:17:23.477","modified":"2026-09-09T21:09:13.080","status":"Deferred","description":"Colord is a tiny yet powerful tool for high-performance color manipulations and conversions. Prior to 2.9.4, synchronous CSS color string matchers in src/colorModels/rgbString.ts, src/colorModels/hslString.ts, src/colorModels/hwbString.ts, src/colorModels/lchString.ts, and src/colorModels/cmykString.ts use the ambiguous numeric regular expression ([+-]?\\d*.?\\d+), allowing the same digits to be divided between overlapping quantifiers in quadratically many ways when malformed input is rejected. An attacker who can supply an unbounded color string to colord(), getFormat(), isEqual(), mix(), or contrast(), including through a request body, JSON field, or uploaded stylesheet, can block the processing thread with a multi-kilobyte payload. The affected matchers are parseRgbaString, parseHslaString, parseHwbaString, parseLchaString, and parseCmykaString. This issue is fixed in version 2.9.4.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N","score":6.9},"cvss_v3":null,"cwes":["CWE-1333"],"references":["https://github.com/omgovich/colord/commit/87018089515ed66a85b1a95c3c7c3fd69a25bac2","https://github.com/omgovich/colord/pull/141","https://github.com/omgovich/colord/security/advisories/GHSA-2wm5-q62r-hmrv"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:52:03.409947763+00:00"},"epss":{"cve":"CVE-2026-85062","score":0.00507,"percentile":0.43256,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-2wm5-q62r-hmrv","url":"https://osv.dev/vulnerability/GHSA-2wm5-q62r-hmrv","summary":"Colord: Slow rejection of oversized malformed color strings","modified":"2026-09-08T21:00:06.239800217Z","packages":[{"ecosystem":"npm","name":"colord","purl":"pkg:npm/colord","ranges":["<2.9.4"],"fixed":["2.9.4"]}]}],"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).
