Prior to 4.5.115, the create_agent_centric_tools() function returns tools (like acp_create_file) that process file content using template rendering. When user input from agent.start() is passed directly into these tools without escaping, template expressions in the input are executed rather than treated as literal text. This vulnerability is fixed in 4.5.115."}], "lastModified": "2026-04-22T16:51:30.870", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:praison:praisonai:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "B0754891-B47D-441D-A0E6-710A49389AE4", "versionEndIncluding": "4.5.114"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
