{"id":"PYSEC-2026-402","summary":"Remote Code Execution via path traversal bypass in lollms","details":"CVE-2024-4320 describes a vulnerability in the parisneo/lollms software, specifically within the `ExtensionBuilder().build_extension()` function. The vulnerability arises from the `/mount_extension` endpoint, where a path traversal issue allows attackers to navigate beyond the intended directory structure. This is facilitated by the `data.category` and `data.folder` parameters accepting empty strings (`\"\"`), which, due to inadequate input sanitization, can lead to the construction of a `package_path` that points to the root directory. Consequently, if an attacker can create a `config.yaml` file in a controllable path, this path can be appended to the `extensions` list and trigger the execution of `__init__.py` in the current directory, leading to remote code execution. The vulnerability affects versions from 5.9.0, and has been addressed in version 9.5.1.","aliases":["CVE-2024-5443","GHSA-mvrm-fh8q-6wr2"],"modified":"2026-07-01T20:22:56.781723Z","published":"2026-06-29T11:50:41.906697Z","references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-5443"},{"type":"WEB","url":"https://github.com/parisneo/lollms/commit/2d0c4e76be93195836ecd0948027e791b8a2626f"},{"type":"PACKAGE","url":"https://github.com/ParisNeo/lollms"},{"type":"WEB","url":"https://huntr.com/bounties/db52848a-4dbe-4110-a981-03739834bf45"},{"type":"PACKAGE","url":"https://pypi.org/project/lollms"},{"type":"ADVISORY","url":"https://github.com/advisories/GHSA-mvrm-fh8q-6wr2"}],"affected":[{"package":{"name":"lollms","ecosystem":"PyPI","purl":"pkg:pypi/lollms"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.9.0"},{"fixed":"9.5.1"}]}],"versions":["5.9.0","5.9.1","5.9.2","5.9.3","5.9.4","5.9.5","6.0.0","6.0.1","6.0.2","6.0.3","6.0.5","6.0.6","6.0.7","6.0.8","6.0.9","6.1.1","6.2.0","6.4.0","6.5.0","6.5.1","6.5.2","6.6.0","6.7.0","6.9.0","7.2.0","9.3.0","9.5.0"],"database_specific":{"source":"https://github.com/pypa/advisory-database/blob/main/vulns/lollms/PYSEC-2026-402.yaml"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
