CVE-2025-58430: listmonk Vulnerable to CSRF to XSS Chain That Can Lead to Admin Account Takeover
Noroxi assessment
Priority: Monitor (action score 34/100)
- The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
- Probability of exploitation in the next 30 days: 0.13% (FIRST EPSS).
- Anyone who can reach it over the internet can trigger it. No account or password is required. No special conditions are required; it is repeatable.
- Fixed version: govulncheck-vulndb (openSUSE:Leap 15.6) 0.0.20250918T182144-150000.1.107.1; govulncheck-vulndb (openSUSE:Tumbleweed) 0.0.20250917T170349-1.1; govulncheck-vulndb (SUSE:Linux Enterprise Module for Package Hub 15 SP6) 0.0.20250918T182144-150000.1.107.1.
Low priority for now. Upgrade to govulncheck-vulndb (openSUSE:Leap 15.6) 0.0.20250918T182144-150000.1.107.1; govulncheck-vulndb (openSUSE:Tumbleweed) 0.0.20250917T170349-1.1; govulncheck-vulndb (SUSE:Linux Enterprise Module for Package Hub 15 SP6) 0.0.20250918T182144-150000.1.107.1 or later.
Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it
Primary sources: NVD · CVE.org · FIRST EPSS
listmonk is a standalone, self-hosted, newsletter and mailing list manager. In versions up to and including 1.1.0, every http request in addition to the session cookie `session` there included `nonce`. The value is not checked and validated by the backend, removing `nonce` allows the requests to be processed correctly. This may seem harmless, but if chained to other vulnerabilities it can become a critical vulnerability. Cross-site request forgery and cross-site scripting chained together can result in improper admin account creation. As of time of publication, no patched versions are available.
