{"apiVersion":"1.0","identifier":"CVE-2026-53759","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.","publishedAt":"2026-08-18T21:16:35","lastModifiedAt":"2026-08-21T20:16:37","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-53759","cvssScore":2,"cvssVector":"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/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","epssProbability":0.00184,"riskScore":0.2,"affectedProduct":"linuxfabrik-lib","affectedVersions":"<4.2.0","vulnerabilityType":"Library","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-53759","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-53759","en":"https://www.redsauce.net/en/cves/CVE-2026-53759","fr":"https://www.redsauce.net/fr/cves/CVE-2026-53759","pt":"https://www.redsauce.net/pt/cves/CVE-2026-53759","de":"https://www.redsauce.net/de/cves/CVE-2026-53759","sk":"https://www.redsauce.net/sk/cves/CVE-2026-53759","el":"https://www.redsauce.net/el/cves/CVE-2026-53759"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-53759"}}
