An unprivileged user can supply a full path to a writable directory, which lets aptd read a file as root. Having a symlink in place results in an error message if the file exists, and no error otherwise. This way an unprivileged user can check for the existence of any files on the system as root.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","score":3.3},"cwes":["CWE-22"],"references":["https://ubuntu.com/security/notices/USN-4537-1","https://www.eyecontrol.nl/blog/the-story-of-3-cves-in-ubuntu-desktop.html","https://ubuntu.com/security/notices/USN-4537-1","https://www.eyecontrol.nl/blog/the-story-of-3-cves-in-ubuntu-desktop.html"],"products":["aptdaemon_project:aptdaemon"],"source":"nvd","synced_at":"2026-10-19T21:11:20.317016139+00:00"},"epss":{"cve":"CVE-2020-15703","score":0.0049,"percentile":0.42146,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-wpmr-q825-x4c6","url":"https://osv.dev/vulnerability/GHSA-wpmr-q825-x4c6","summary":"aptdaemon Information Disclosure via Improper Input Validation in Transaction class","modified":"2026-07-07T11:56:14.578428766Z","packages":[{"ecosystem":"PyPI","name":"aptdaemon","purl":"pkg:pypi/aptdaemon","ranges":["<1.1.1"],"fixed":["1.1.1"]}]},{"id":"PYSEC-2026-783","url":"https://osv.dev/vulnerability/PYSEC-2026-783","summary":"aptdaemon Information Disclosure via Improper Input Validation in Transaction class","modified":"2026-07-07T11:45:42.953970163Z","packages":[{"ecosystem":"PyPI","name":"aptdaemon","purl":"pkg:pypi/aptdaemon","ranges":["<1.1.1"],"fixed":["1.1.1"]}]}],"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).
