{"id":"CVE-2026-50181","state":"PUBLISHED","title":"Langroid: Path traversal in the file tools allows read/write outside configured current directory","description":"Langroid is a framework for building large-language-model-powered applications. Prior to version 0.64.0, Langroid's `ReadFileTool` and `WriteFileTool` appear to treat `curr_dir` as the intended working-directory boundary for file operations. However, the tools only change the process working directory to `curr_dir` and then operate on the user-supplied `file_path` without resolving and enforcing that the final path remains inside `curr_dir`. As a result, a tool caller can supply path traversal sequences such as `../secret.txt` to read files outside the configured current directory, or `../written_by_tool.txt` to write files outside that directory. This can impact applications that expose Langroid file tools to an LLM agent, user-controlled tool call, or delegated coding/documentation agent while relying on `curr_dir` to restrict file access to a project/workspace directory. Version 0.64.0 patches the issue.","publishedAt":"2026-07-09T23:44:46.559Z","updatedAt":"2026-07-14T01:25:33.853Z","severity":{"score":7.1,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["langroid langroid"],"affected":[{"vendor":"langroid","product":"langroid","versions":[{"version":"< 0.64.0","status":"affected"}]}],"references":["https://github.com/langroid/langroid/security/advisories/GHSA-fg23-3346-88f5","https://github.com/langroid/langroid/commit/56e2756ecab70a70a7e6edbee2f2187b8484683e"],"weaknesses":["CWE-22","CWE-23"],"ingestedAt":"2026-10-29T20:12:16.098Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/50xxx/CVE-2026-50181.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-50181","state":"PUBLISHED","datePublished":"2026-07-09T23:44:46.559Z","dateUpdated":"2026-07-14T01:25:33.853Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-06-03T22:05:13.644Z"},"containers":{"cna":{"title":"Langroid: Path traversal in the file tools allows read/write outside configured current directory","descriptions":[{"lang":"en","value":"Langroid is a framework for building large-language-model-powered applications.
