{"cve":"CVE-2026-55523","nvd":{"published":"2026-08-05T20:17:10.690","modified":"2026-10-24T16:10:00.153","status":"Deferred","description":"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.","cvss_v4":{"vector":"CVSS:4.0/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},"cvss_v3":null,"cwes":["CWE-918"],"references":["https://github.com/MervinPraison/PraisonAI/security/advisories/GHSA-8hjw-25cg-g52h","https://github.com/MervinPraison/PraisonAI/security/advisories/GHSA-8hjw-25cg-g52h"],"products":[],"source":"nvd","synced_at":"2026-10-24T16:53:34.184483516+00:00"},"epss":{"cve":"CVE-2026-55523","score":0.00468,"percentile":0.40245,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-8hjw-25cg-g52h","url":"https://osv.dev/vulnerability/GHSA-8hjw-25cg-g52h","summary":"praisonaiagents has a `web_crawl` SSRF protection bypass via unchecked redirect targets","modified":"2026-09-10T12:25:41.108195965Z","packages":[{"ecosystem":"PyPI","name":"praisonaiagents","purl":"pkg:pypi/praisonaiagents","ranges":[">=1.5.128 <1.6.58"],"fixed":["1.6.58"]}]},{"id":"PYSEC-2026-3900","url":"https://osv.dev/vulnerability/PYSEC-2026-3900","summary":"praisonaiagents has a `web_crawl` SSRF protection bypass via unchecked redirect targets","modified":"2026-09-10T12:15:07.962296222Z","packages":[{"ecosystem":"PyPI","name":"praisonaiagents","purl":"pkg:pypi/praisonaiagents","ranges":[">=1.5.128 <1.6.58"],"fixed":["1.6.58"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
