CVE-2026-55523 Details
Description
PraisonAI is a multi-agent teams system. In versions 1.5.128 through 1.6.57, the praisonaiagents.tools.web_crawl_tools.web_crawl() function is vulnerable to server-side request forgery. While it validates the initially supplied URL and blocks direct loopback and private destinations, its default httpx fallback uses httpx.Client(follow_redirects=True) and does not revalidate intermediate or final redirect targets. An attacker who can influence a URL passed to web_crawl(), directly or through an agent or tool workflow, can supply an attacker-controlled public URL that passes the initial host check and then redirects to loopback, private-network, or cloud metadata endpoints reachable from the host, with the redirected response body returned in the web_crawl() result. This constitutes an incomplete fix and patch bypass for the previously disclosed web_crawl SSRF class (GHSA-qq9r-63f6-v542 / CVE-2026-40160 and GHSA-8f4v-xfm9-3244), since the guard validates only the requested URL and not the destination actually fetched after redirection. This issue has been fixed in version 1.6.58.
A server-side request forgery (SSRF) vulnerability has been identified in the PraisonAI multi-agent system, specifically in the web_crawl() function of the praisonaiagents.tools.web_crawl_tools module. This vulnerability affects PraisonAI versions 1.5.128 through 1.6.56. The issue arises because, while the function initially validates the supplied URL and blocks direct loopback and private destinations, the default httpx client used for fetching URLs follows redirects without revalidating the final destination. As a result, an attacker can exploit this by providing a public URL that redirects to loopback, private-network, or cloud metadata endpoints, with the response body returned in the web_crawl() result. This vulnerability represents an incomplete fix and patch bypass for a previously disclosed SSRF issue in the same function.
Users can update to PraisonAI version 1.6.58 or later, where this vulnerability has been fixed.
