If an attacker could influence a tool-produced ReplyPayload.mediaUrl, the webchat audio embedding helper could read an audio-like file under the size cap and return it base64-encoded, crossing from model or tool output into a host file read.","solution":"Upgrade to openclaw@2026.4.15 or later; the latest public release, 2026.4.21, is fixed. Before upgrading, avoid exposing webchat sessions to untrusted prompt or tool content that can influence reply media URLs.","labels":["security"],"sourceUrl":"https://github.com/advisories/GHSA-gfg9-5357-hv4c","publishedAt":"2026-04-29T21:34:39.000Z","cveId":null,"cweIds":null,"cvssScore":null,"cvssSeverity":"medium","severity":"medium","attackType":["prompt_injection"],"issueType":"vulnerability","affectedPackages":["openclaw@<= 2026.4.14 (fixed: 2026.4.15)"],"affectedPackageNames":["openclaw"],"affectedPackageRefs":["npm:openclaw"],"affectedVendors":[],"affectedVendorsRaw":["OpenClaw"],"classifierModel":"claude-haiku-5-5","classifierPromptVersion":"v4","summaryPromptVersion":"v2","headline":null,"headlinePromptVersion":null,"cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":null,"epssScore":null,"epssCheckedAt":null,"kevDateAdded":null,"advisoryAliases":["GHSA-gfg9-5357-hv4c"],"affectedPackagesSource":null,"affectedPackagesCheckedAt":null,"patchAvailable":true,"disclosureDate":"2026-04-29T21:34:39.000Z","fixReleasedAt":"2026-04-16T22:11:23.282Z","daysToFix":-13,"fixCheckedAt":"2026-10-29T21:37:10.290Z","capecIds":null,"crossRefCount":0,"attackSophistication":"moderate","impactType":["confidentiality"],"aiComponentTargeted":"agent","llmSpecific":true,"classifierConfidence":0.85,"researchCategory":null,"atlasIds":["AML.T0051"],"fixes":[{"ecosystem":"npm","name":"openclaw","fixedVersion":"2026.4.15","matchedVersion":"2026.4.15","fixReleasedAt":"2026-04-16T22:11:23.282Z","daysToFix":-13,"match":"ecosystem","source":"registry","status":"found","checkedAt":"2026-10-29T21:37:10.142Z"}]}}
