{"data":{"id":"9260670a-0a48-413e-af1c-4131f82ff183","title":"P2Patch: Exploit-Guided Vulnerability Repair","summary":"P2Patch is a generative adversarial repair system in which an exploitation agent builds a proof of vulnerability, a patching agent repairs the program, and the exploitation agent then searches for a distinct same-vulnerability exploit against the patch. Across 101 C/C++ and Java CVE subjects, the loop surfaced a distinct confirmed exploit in 41% of runs after the original proof of vulnerability was blocked. Held-out fix-closed coverage rose from 78.1% under single-pass Claude Code repair to 84.7%, and beyond-upstream coverage rose from 42.1% to 62.5%.","solution":"N/A -- no mitigation discussed in source.","labels":["research","security"],"sourceUrl":"https://arxiv.org/abs/2610.20245v1","publishedAt":"2026-10-14T14:19:21.000Z","cveId":null,"cweIds":null,"cvssScore":null,"cvssSeverity":null,"severity":"info","attackType":[],"issueType":"research","affectedPackages":null,"affectedPackageNames":null,"affectedPackageRefs":null,"affectedVendors":[],"affectedVendorsRaw":["Claude Code"],"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":null,"affectedPackagesSource":null,"affectedPackagesCheckedAt":null,"patchAvailable":null,"disclosureDate":"2026-10-14T14:19:21.000Z","capecIds":null,"crossRefCount":0,"attackSophistication":"advanced","impactType":null,"aiComponentTargeted":"agent","llmSpecific":true,"classifierConfidence":0.9,"researchCategory":"preprint","atlasIds":null}}
