• CVE-2026-61430: 0.25% estimated exploitation activity in the next 30 days; percentile 16.93 (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 PraisonAI's webcrawl agent tool performs a server-side HTTP fetch of an agent/attacker-influenced URL. SSRF is meant to be prevented by issafecrawlurl(), which resolves the hostname and rejects private/loopback/link-local IPs at validation time. The validated value is the URL string (not a pinned IP); the fetch backend then re-resolves the hostname at connection time. Because validation and connection perform two independent DNS resolutions, a DNS-rebinding domain that returns a public IP during validation and an internal IP during the fetch fully bypasses the guard, and the internal HTTP response body is returned to the caller. This is SSRF with internal response disclosure (read-back) — not blind SSRF. Runtime-confirmed against PraisonAI 4.6.63; the crawl response returned the controlled internal markers PRAISONAIINTERNALSECRETCANARY7f3a91 / FAKEINTERNALTOKENDONOTUSE7f3a91. Severity High. Reachable by any actor who can influence the URL an agent crawls (e.g. a…

# Patch Next advisory brief: CVE-2026-61430

Advisory: PraisonAI: DNS rebinding bypass in `web_crawl` SSRF protection allows internal response disclosure
IDs: CVE-2026-61430, GHSA-qg25-6gc4-48mg
Record: https://patchnext.com/advisories/cve-2026-61430 (revision 3, source checked 26 Oct 2026, 13:55 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 8.5)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: praisonaiagents 1.6.78. A vendor fix does not mean a deployment is fixed.

## Affected components
- PyPI praisonaiagents: affected <= 1.6.77; fixed in 1.6.78

## 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.
