Versions 15.3.11 and below include a critical deserialization vulnerability in the Helpdesk module (which is not enabled by default). This vulnerability allows Remote Code Execution (RCE) by an authenticated user with staff security level due to using Python's pickle module in helpdesk /reports/. The original CVE-2020-14942 was incompletely patched. While ticket_list() was fixed to use safe JSON deserialization, the run_report() function still uses unsafe pickle.loads(). The impact is limited to the permissions of the user running the application, typically www-data, which generally lacks write (except for upload directories) and execute permissions. This issue has been fixed in version 15.3.12.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:U/C:H/I:H/A:H","score":6.8},"cwes":["CWE-94","CWE-502"],"references":["https://docs.python.org/3/library/pickle.html#restricting-globals","https://github.com/advisories/GHSA-jqmc-fxxp-r589","https://github.com/tendenci/tendenci/commit/23d9fd85ab7654e9c83cfc86cb4175c0bd7a77f1","https://github.com/tendenci/tendenci/commit/2ff0a457614944a1b417081c543ea4c5bb95d636","https://github.com/tendenci/tendenci/commit/63e1b84a5b163466d1d8d811d35e7021a7ca0d0e"],"products":["tendenci:tendenci"],"source":"nvd","synced_at":"2026-10-19T22:21:16.563232421+00:00"},"epss":{"cve":"CVE-2026-23946","score":0.00837,"percentile":0.57783,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-339m-4qw5-j2g3","url":"https://osv.dev/vulnerability/GHSA-339m-4qw5-j2g3","summary":"Tendenci Affected by Authenticated Remote Code Execution via Pickle Deserialization","modified":"2026-07-07T17:56:39.916307506Z","packages":[{"ecosystem":"PyPI","name":"tendenci","purl":"pkg:pypi/tendenci","ranges":["<15.3.12"],"fixed":["15.3.12"]}]},{"id":"PYSEC-2026-1950","url":"https://osv.dev/vulnerability/PYSEC-2026-1950","summary":"Tendenci Affected by Authenticated Remote Code Execution via Pickle Deserialization","modified":"2026-07-07T17:48:12.950112553Z","packages":[{"ecosystem":"PyPI","name":"tendenci","purl":"pkg:pypi/tendenci","ranges":["<15.3.12"],"fixed":["15.3.12"]}]}],"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).
