Summary

crawlseo before version 0.2.5 contains a cleartext storage vulnerability that allows attackers with database read access to obtain Google OAuth access and refresh tokens stored unencrypted in the User.googleTokens column. Attackers can read the plaintext long-lived refresh tokens from a compromised or exposed Postgres database to gain indefinite, unauthenticated access to all registered users' Google Search Console data.

Risk Assessment

Exposure of OAuth tokens could allow an attacker persistent access to all users' Google Search Console data.

Recommendation

Update crawlseo to version 0.2.5 or later, encrypt stored tokens, and revoke exposed OAuth tokens.

Other vulnerabilities in crawlseo

CVE-2026-115411Medium
crawlseo before version 0.2.4 contains a server-side request forgery vulnerability in its crawler engine where isPrivateIp() fails to block reserved IP ranges such as RFC 6598 Carrier-Grade NAT, RFC 6890, TEST-NET ranges and certain IPv6 addresses, and additionally fails to pin the validated address for the actual outbound connection, allowing a TOCTOU DNS rebinding bypass. An authenticated attacker can add a malicious domain that resolves to an internal or restricted address, trigger a crawl to reach internal services or cloud metadata endpoints like 169.254.169.254, and retrieve the fetched page's title, description, headings, status code and links through the crawl results API, enabling internal network reconnaissance.
