• CVE-2026-55525: 0.51% estimated exploitation activity in the next 30 days; percentile 43.33 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

Summary webcrawl (an exported, model-callable tool) validates only the INITIAL URL's resolved IP against a private/loopback blocklist, then fetches with httpx.Client(followredirects=True) and never re-validates redirect targets. An attacker who controls the agent's crawl target (a malicious task, or prompt injection inside any page the agent already crawls) supplies a public URL that HTTP 302-redirects to an internal address. httpx follows the redirect, fetches the internal resource (cloud metadata 169.254.169.254, localhost services, internal APIs), and returns its body into the agent context. This bypasses the SSRF protection added to fix the earlier webcrawl SSRF reports, so it is an incomplete fix for that class. httpx is the default crawl provider on a stock pip install praisonaiagents, so no provider configuration is required. Details 1. The agent is asked (or prompt-injected) to crawl https://attacker.example/r, which the source accepts because attacker.example resolves to a…

# Patch Next advisory brief: CVE-2026-55525

Advisory: praisonaiagents web_crawl vulnerable to SSRF via redirect-following
IDs: CVE-2026-55525, GHSA-5r34-2g38-6569
Record: https://patchnext.com/advisories/cve-2026-55525 (revision 1, source checked 26 Oct 2026, 13:50 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 7.5)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: praisonaiagents 1.6.58. A vendor fix does not mean a deployment is fixed.

## Affected components
- PyPI praisonaiagents: affected < 1.6.58; fixed in 1.6.58

## Suggested inspection (read-only)
- `python -m pip show praisonaiagents`: prints the installed version. Run with the environment that serves production active.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on praisonaiagents.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://github.com/advisories/GHSA-5r34-2g38-6569 (GitHub-reviewed advisory GHSA-5r34-2g38-6569 lists affected ranges: PyPI praisonaiagents >=0 <1.6.58)
