CVE-2026-55525: CWE-918: Server-Side Request Forgery (SSRF) in MervinPraison PraisonAI
Description
CVE-2026-55525 is a Server-Side Request Forgery (SSRF) vulnerability in MervinPraison PraisonAI, a multi-agent teams system. The vulnerability exists because the web_crawl function only validates the initial URL, but does not revalidate redirect targets when following redirects. This allows an attacker who can influence the crawl target to redirect requests to internal resources such as loopback addresses, private networks, or cloud metadata services, even when ALLOW_LOCAL_CRAWL is disabled. The internal response is then returned to the agent context. This issue is fixed in PraisonAI version 1.6.58.

Technical Analysis
PraisonAI versions prior to 1.6.58 contain an SSRF vulnerability (CWE-918) in the web_crawl function. The function validates only the initial URL before using httpx.Client with follow_redirects enabled. Redirect targets are not revalidated, enabling attackers who control the crawl target to cause the system to fetch internal network resources or cloud metadata endpoints. The fetched internal response is exposed to the agent context, potentially leaking sensitive internal information. The vulnerability is addressed in version 1.6.58.
Potential Impact
An attacker able to influence the crawl target can exploit this SSRF vulnerability to access internal network resources or cloud metadata services that should be inaccessible. This can lead to unauthorized disclosure of sensitive internal information. The CVSS score of 7.5 (high) reflects the network attack vector, low complexity, no privileges required, no user interaction, and high confidentiality impact. There is no indication of integrity or availability impact.
Mitigation Recommendations
A fix is available in PraisonAI version 1.6.58. Users should upgrade to version 1.6.58 or later to remediate this vulnerability. No other official remediation or temporary fixes are documented. Until upgrading, avoid exposing the web_crawl function to untrusted inputs that could influence crawl targets.
