{"cve":"CVE-2026-53759","nvd":{"published":"2026-08-18T21:16:35.880","modified":"2026-10-22T21:09:59.367","status":"Deferred","description":"linuxfabrik-lib provides Python modules for database access, caching, shell execution, and API integrations. Prior to version 4.2.0, db_sqlite.py created SQLite databases at predictable paths in the shared /tmp directory and followed attacker-created symbolic links at those paths. An attacker who controls a local monitoring account can create a symlink such as /tmp/linuxfabrik-monitoring-plugins-docker-stats.db and then trigger a sudo-authorized plugin, causing the root process to create or modify the symlink target. The primitive can overwrite arbitrary paths, cause denial of service, or manipulate an existing SQLite database through a crafted rollback journal or write-ahead log. The Monitoring Plugins integration also moved plugin caches through lib.db_sqlite.get_db_path() so they use the secured per-user directory. This issue is fixed in version 4.2.0.","cvss_v4":{"vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:P","score":2.0},"cvss_v3":null,"cwes":["CWE-377"],"references":["https://github.com/Linuxfabrik/lib/blob/main/CHANGELOG.md#v420---2026-06-02","https://github.com/Linuxfabrik/lib/commit/1e3ca61d45e37ef118aa0c107b420ef74458697e","https://github.com/Linuxfabrik/lib/releases/tag/v4.2.0","https://github.com/Linuxfabrik/monitoring-plugins/security/advisories/GHSA-r35r-fpx2-jgr4","https://github.com/Linuxfabrik/monitoring-plugins/security/advisories/GHSA-r35r-fpx2-jgr4"],"products":[],"source":"nvd","synced_at":"2026-10-23T16:39:26.291718493+00:00"},"epss":{"cve":"CVE-2026-53759","score":0.00191,"percentile":0.08668,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-r35r-fpx2-jgr4","url":"https://osv.dev/vulnerability/GHSA-r35r-fpx2-jgr4","summary":"Linuxfabrik Monitoring Plugins allow insecure creation of SQLite databases","modified":"2026-07-13T16:43:43.292732354Z","packages":[{"ecosystem":"PyPI","name":"linuxfabrik-lib","purl":"pkg:pypi/linuxfabrik-lib","ranges":["<4.2.0"],"fixed":["4.2.0"]}]},{"id":"PYSEC-2026-2596","url":"https://osv.dev/vulnerability/PYSEC-2026-2596","summary":"Linuxfabrik Monitoring Plugins allow insecure creation of SQLite databases","modified":"2026-07-13T16:32:03.548924943Z","packages":[{"ecosystem":"PyPI","name":"linuxfabrik-lib","purl":"pkg:pypi/linuxfabrik-lib","ranges":["<4.2.0"],"fixed":["4.2.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
