Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
cPanel before 60.0.25 allows self stored XSS in SSL_listkeys (SEC-182).

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

cPanel before version 60.0.25 contains a stored cross-site scripting (XSS) vulnerability in the SSL_listkeys function (SEC-182). The vulnerability allows injection of malicious scripts that are stored and executed when the user accesses their own key listings.

MitigationUpgrade cPanel to version 60.0.25 or later to patch the XSS vulnerability in SSL_listkeys.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Check cPanel version
    Run /usr/local/cpanel/cpanel -V or cat /usr/local/cpanel/version to obtain the installed cPanel version number
    Affected if The installed version falls within these ranges: 11.54.0.0 to 11.54.0.32, 55.9999.61 to 56.0.38, 57.9999.48 to 58.0.36, or 59.9999.58 to 60.0.24
  2. Confirm SSL keys feature is accessible
    Verify that the cPanel SSL/TLS key management interface (SSL_listkeys function) is available to user accounts by checking if users can access the SSL Wizard or SSL/TLS section in cPanel
    Affected if The SSL/TLS feature is enabled and accessible to users in the cPanel interface
  3. Inspect SSL key entries for injection markers
    Review stored SSL keys in /var/cpanel/ssl/cpanel/ or via cPanel API for unusual characters, script tags, or encoded payloads in key descriptions or filenames that could indicate prior exploitation
    Affected if Any SSL key entries contain suspicious content such as script tags, event handlers, or encoded JavaScript that was injected into key metadata

A user is affected if their cPanel version is within the affected ranges AND the SSL/TLS key listing feature is accessible to user accounts, with exploitation indicated by suspicious script content in stored SSL key data.
