Redirect-target SSRF protection bypass in PraisonAI SpiderTools

IdentifiersCVE-2026-57115CWE-918

CVE-2026-57115 is a server-side request forgery vulnerability in SpiderTools within PraisonAI. The flaw arises because the initial user-influenced URL is subjected to SSRF validation, but subsequent HTTP redirect destinations are followed automatically without applying the same validation logic to each redirect hop. As a result, an attacker can supply a benign external URL that responds with a redirect to an otherwise blocked destination, bypassing protections intended to prevent access to loopback, private-network, and metadata endpoints. The issue affects URL-processing functionality exposed through SpiderTools methods including scrape_page(), extract_links(), crawl(), and extract_text().

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation allows an attacker to induce the PraisonAI process to issue HTTP requests to internal or otherwise restricted destinations reachable from the host. This can expose response bodies from loopback-only services, permit probing or reading services on private network ranges, and enable access to link-local or cloud metadata endpoints where reachable. The primary demonstrated consequence is disclosure of data returned by internal HTTP services, with additional risk of internal network reconnaissance depending on deployment topology and reachable services.

Mitigation

If you can’t patch tonight, do this now.

Until a fixed version is deployed, prevent untrusted users or workflows from supplying URLs to SpiderTools functions such as scrape_page(), extract_links(), crawl(), and extract_text(). Disable automatic HTTP redirects where possible, or process redirects manually while enforcing SSRF validation on every Location target before following it. Reduce blast radius by restricting outbound network access from the PraisonAI host to internal, loopback, private, and metadata services through network policy, firewalling, or workload isolation.

Remediation

Patch, then assume compromise.

Upgrade the PyPI package praisonaiagents to version 1.6.59 or later. If patching must be performed manually, disable automatic redirect following in SpiderTools requests or implement explicit redirect handling that validates every redirect target with the same SSRF protection logic applied to the original URL. Regression testing should verify both direct rejection of restricted destinations and rejection of redirects from public URLs to loopback, private, and metadata targets across scrape_page() and dependent callers.
