CVE Alert: CVE-2024-13807 – xagio – Xagio SEO – AI Powered SEO

Risk verdict

Unauthenticated remote access to backup data via the vulnerable plugin creates a high risk of data exposure; patching should be treated as urgent.

Why this matters

Backups can contain the entire database, site files, and configuration details, enabling significant data loss or leakage if retrieved by unauthorised actors. The issue supports opportunistic data theft at scale and could have compliance and reputational consequences for affected sites.

Most likely attack path

An unauthenticated attacker can directly request web-accessible backup files resulting from the plugin’s flawed backup handling. No user interaction or privileges are required, and an exposed backup endpoint suffices; exploitation does not alter integrity or availability, but yields sensitive information and potential lateral movement through disclosed data.

Who is most exposed

WordPress installations running Xagio SEO with backups stored in web-accessible locations (common on shared hosting or misconfigured servers) are at greatest risk, particularly those with lax directory protections or exposed backup naming.

Detection ideas

• Unusual GET requests targeting known backup file patterns and directories.
• Access logs showing frequent retrieval of backup-like files without corresponding user activity.
• Large or unexpected data transfers from plugin backup endpoints.
• 403/404 patterns around backup URLs followed by successful fetches from odd IPs.

Mitigation and prioritisation

• Update to patched version (or remove/disable backups feature) promptly.
• Move backups out of the web root; enforce access controls and authentication for backup endpoints.
• Apply server-side protections (deny listing, rate limiting, IP allowlists for backup paths).
• Validate and test change in a staging environment before production rollout; perform a targeted patch window.
• If KEV is present or EPSS ≥ 0.5, treat as priority 1.
