{"id":"CVE-2026-73089","summary":"Browserslist: Unbounded memory growth (no cache eviction) via distinct query results, leading to eventual OOM","details":"Browserslist is a configuration tool for sharing target browsers and Node.js versions between front-end tools. Prior to 4.28.7, index.js retains every distinct `(queries, context)` result in cache and every parseQueries() AST in parseCache without a size cap, TTL, or eviction, allowing an attacker who can influence repeated browserslist() query values, including valid since `\u003cyear\u003e-\u003cmonth\u003e-\u003cday\u003e` queries, to bypass the caller-controlled BROWSERSLIST_DISABLE_CACHE mitigation and cause linear memory growth followed by an out-of-memory process crash. This issue is fixed in version 4.28.7.","aliases":["GHSA-c83g-rgw3-j3cx"],"modified":"2026-08-15T11:31:02.305837247Z","published":"2026-08-11T17:05:38.760Z","database_specific":{"cwe_ids":["CWE-770"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/73xxx/CVE-2026-73089.json","cna_assigner":"GitHub_M"},"references":[{"type":"WEB","url":"https://github.com/browserslist/browserslist/releases/tag/4.28.7"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/73xxx/CVE-2026-73089.json"},{"type":"ADVISORY","url":"https://github.com/browserslist/browserslist/security/advisories/GHSA-c83g-rgw3-j3cx"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-73089"},{"type":"FIX","url":"https://github.com/browserslist/browserslist/commit/f2931a3ff2a3a31abf84ef01a7400b270aad6405"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/browserslist/browserslist","events":[{"introduced":"0"},{"fixed":"f2931a3ff2a3a31abf84ef01a7400b270aad6405"},{"fixed":"b637868045806d2fba4c24eb0060e4cc8b1db276"}],"database_specific":{"source":["AFFECTED_FIELD","REFERENCES"],"extracted_events":[{"introduced":"0"},{"fixed":"4.28.7"}]}}],"versions":["4.28.6","4.28.5","4.28.4","4.28.3","4.28.2","4.28.1","4.28.0","4.27.0","4.26.3","4.26.2","4.26.1","4.26.0","4.25.4","4.25.3","4.25.2","4.25.1","4.25.0","4.24.5","4.24.3","4.24.2","4.24.1","4.24.0","4.23.3","4.23.2","4.23.1","4.23.0","4.22.3","4.22.2","4.22.1","4.22.0","4.21.11","4.21.10","4.21.9","4.21.8","4.21.7","4.21.6","4.21.5","4.21.4","4.21.3","4.21.2","4.21.1","4.21.0","4.20.4","4.20.3","4.20.2","4.20.1","4.20.0","4.19.3","4.19.2","4.19.1","4.19.0","4.18.1","4.18.0","4.17.6","4.17.5","4.17.4","4.17.3","4.17.2","4.17.1","4.17.0","4.16.8","4.16.7","4.16.6","4.16.5","4.16.4","4.16.3","4.16.2","4.16.1","4.16.0","4.15.0","4.14.7","4.14.6","4.14.5","4.14.4","4.14.3","4.14.2","4.14.1","4.14.0","4.13.0","4.12.2","4.12.1","4.12.0","4.11.1","4.11.0","4.10.0","4.9.1","4.9.0","4.8.7","4.8.6","4.8.5","4.8.4","4.8.3","4.8.2","4.8.1","4.8.0","4.7.3","4.7.2","4.7.1","4.7.0","4.6.6","4.6.5","4.6.4","4.6.3","4.6.2","4.6.1","4.6.0","4.5.6","4.5.5","4.5.3","4.5.2","4.5.1","4.5.0","4.4.2","4.4.1","4.4.0","4.3.7","4.3.6","4.3.5","4.3.3","4.3.2","4.3.1","4.3.0","4.2.1","4.2.0","4.1.2","4.1.1","4.1.0","4.0.2","4.0.1","4.0.0","3.2.8","3.2.7","3.2.6","3.2.5","3.2.4","3.2.3","3.2.2","3.2.1","3.2.0","3.1.2","3.1.1","3.1.0","3.0.0","2.11.3","2.11.2","2.11.1","2.11.0","2.10.2","2.10.1","2.10.0","2.9.1","2.9.0","2.8.0","2.7.0","2.6.1","2.6.0","2.5.1","2.5.0","2.4.1","2.4.0","2.3.3","2.3.2","2.3.1","2.3.0","2.2.2","2.2.1","2.2.0","2.1.5","2.1.4","2.1.3","2.1.2","2.1.1","2.1.0","2.0.0","1.7.7","1.7.6","1.7.5","1.7.4","1.7.3","1.7.2","1.7.0","1.6.0","1.5.2","1.5.1","1.5.0","1.4.0","1.3.6","1.3.5","1.3.4","1.3.3","1.3.2","1.3.1","1.3.0","1.2.0","1.1.3","1.1.2","1.1.1","1.1.0","1.0.1","1.0.0","0.5.0","0.4.0","0.3.3","0.3.2","0.3.1","0.3.0","0.2.0","0.1.3","0.1.2","0.1.1","0.1.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-73089.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
