PYSEC-2026-4272 PraisonAI: DNS rebinding bypass in `web_crawl` SSRF protection allows internal response disclosure

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...

PYSEC-2026-4214 Docling has SSRF guard bypass in remote resource fetching (DNS rebinding / multi-record resolution; no IP validation in HTML render mode)

Summary When remote fetching is enabled enableremotefetch=True, together with fetchimages=True or HTML renderpage=True, docling's protection against requests to private and loopback addresses can be bypassed. - The URL check resolves the host name once, to a single IPv4 address. The HTTP request...
