{"id":"CVE-2026-22178","summary":"OpenClaw \u003c 2026.2.19 - ReDoS and Regex Injection via Unescaped Feishu Mention Metadata","details":"OpenClaw versions prior to 2026.2.19 construct RegExp objects directly from unescaped Feishu mention metadata in the stripBotMention function, allowing regex injection and denial of service. Attackers can craft nested-quantifier patterns or metacharacters in mention metadata to trigger catastrophic backtracking, block message processing, or remove unintended content before model processing.","aliases":["GHSA-c6hr-w26q-c636"],"modified":"2026-08-12T03:51:45.709339951Z","published":"2026-03-18T01:34:22.432Z","database_specific":{"cwe_ids":["CWE-1333"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/22xxx/CVE-2026-22178.json","cna_assigner":"VulnCheck"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/22xxx/CVE-2026-22178.json"},{"type":"ADVISORY","url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-c6hr-w26q-c636"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-22178"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/openclaw-redos-and-regex-injection-via-unescaped-feishu-mention-metadata"},{"type":"FIX","url":"https://github.com/openclaw/openclaw/commit/74268489137510b6f6349919d1e197b17290d92c"},{"type":"FIX","url":"https://github.com/openclaw/openclaw/commit/7e67ab75cc2f0e93569d12fecd1411c2961fcc8c"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/openclaw/openclaw","events":[{"introduced":"0"},{"fixed":"2c05cbb43e48ebad03626d3125746fb1b9a8520f"},{"fixed":"74268489137510b6f6349919d1e197b17290d92c"},{"fixed":"7e67ab75cc2f0e93569d12fecd1411c2961fcc8c"}],"database_specific":{"cpe":"cpe:2.3:a:openclaw:openclaw:*:*:*:*:*:node.js:*:*","extracted_events":[{"introduced":"0"},{"fixed":"2026.2.19"}],"source":["CPE_RANGE","REFERENCES"]}}],"versions":["v2026.2.17","v2026.2.15-beta.1","v2026.2.14","v2026.2.13","v2026.2.12","v2026.2.9","v2026.2.6-3","v2026.2.6-2","v2026.2.6-1","v2026.2.6","v2026.2.3","v2026.2.2","v2026.2.1","v2026.1.30","v2026.1.29","v2026.1.24-1","v2026.1.24","v2026.1.23","v2026.1.22","v2026.1.21","v2026.1.20","v2026.1.16-2","v2026.1.15","v2026.1.14-1","v2026.1.13","v2026.1.12-2","v2026.1.12","v2026.1.11-3","v2026.1.11-2","v2026.1.11-1","v2026.1.11","v2026.1.10","v2026.1.9","v2026.1.8","v2026.1.5-3","v2026.1.5-2","v2026.1.5-1","v2026.1.5","v2.0.0-beta5","v2.0.0-beta4","v2.0.0-beta3","v2.0.0-beta2","v2.0.0-beta1","v1.3.0","v1.2.2","v1.2.1","v1.2.0","v1.1.0","v1.0.4","v0.1.3","v0.1.2","v0.1.1","v0.1.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-22178.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:L/SC:N/SI:N/SA:N"}]}
