Lifecycle Timeline
3DescriptionCVE.org
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.
AnalysisAI
Server-side request forgery in PraisonAI's web_crawl() function (versions 1.5.128-1.6.57) allows an attacker who can influence URLs processed by agent or tool workflows to exfiltrate responses from internal services, private network hosts, and cloud metadata endpoints such as AWS IAM credential URLs. This is a confirmed patch bypass of the previously disclosed SSRF class in CVE-2026-40160 and GHSA-8f4v-xfm9-3244, exploiting the fact that the httpx fallback client uses follow_redirects=True without revalidating redirect destinations against the original host blocklist. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires that the attacker can influence a URL processed by web_crawl(), either directly through an API or user-facing input that invokes the function, or indirectly via an agent or tool workflow that incorporates attacker-controlled strings into fetched URLs. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The vendor-provided CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:N/SC:H/SI:N/SA:N, score 7.7) accurately characterizes the attack model: network-reachable, low complexity, no authentication required, with high confidentiality impact on subsequent systems (internal services and cloud infrastructure) rather than on the PraisonAI process itself. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Upgrade PraisonAI to version 1.6.58, which is confirmed by the vendor advisory at https://github.com/MervinPraison/PraisonAI/security/advisories/GHSA-8hjw-25cg-g52h to resolve the redirect-destination revalidation gap. … Detailed patch versions, workarounds, and compensating controls in full report. |
