• CVE-2025-58430: 0.14% estimated exploitation activity in the next 30 days; percentile 3.09 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

Summary Cross-Site Request Forgery (CSRF) is an attack that forces an end user to execute unwanted actions on a web application in which they’re currently authenticated. With a little help of social engineering (such as sending a link via email or chat), an attacker may trick the users of a web application into executing actions of the attacker’s choosing. If the victim is a normal user, a successful CSRF attack can force the user to perform state changing requests like transferring funds, changing their email address, and so forth. If the victim is an administrative account, CSRF can compromise the entire web application. Details During a security evaluation of the webapp, 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. Example…

# Patch Next advisory brief: CVE-2025-58430

Advisory: listmonk: CSRF to XSS Chain can Lead to Admin Account Takeover
IDs: CVE-2025-58430, GHSA-rf24-wg77-gq7w
Record: https://patchnext.com/advisories/cve-2025-58430 (revision 1, source checked 26 Oct 2026, 15:10 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 8.6)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor response not established. A vendor fix does not mean a deployment is fixed.

## Affected components
- Go github.com/knadh/listmonk: affected <= 1.1.0

## Suggested inspection (read-only)
- Go github.com/knadh/listmonk: check the installed version with your package manager.

## Supported action
No complete vendor fix is recorded. Follow the primary source's mitigation guidance and check this record again before closing anything.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on github.com/knadh/listmonk.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://github.com/advisories/GHSA-rf24-wg77-gq7w (GitHub-reviewed advisory GHSA-rf24-wg77-gq7w lists affected ranges: Go github.com/knadh/listmonk >=0 <=1.1.0)
