{"id":"PYSEC-2026-3819","summary":"crewai-tools SSRF redirect bypass exposes internal services","details":"CrewAI before 1.15.1 contains a server-side request forgery vulnerability in the validate_url function that performs one-shot DNS resolution and blocklist checks before returning the original URL unchanged. Attackers can bypass the security filter by supplying URLs that redirect to internal addresses or use DNS rebinding techniques to access internal services and cloud metadata endpoints.","aliases":["CVE-2026-62240","GHSA-mr4r-hcgx-8p4h"],"modified":"2026-09-10T12:15:05.550772476Z","published":"2026-09-10T09:44:50.523376Z","references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-62240"},{"type":"WEB","url":"https://github.com/crewAIInc/crewAI/issues/6520"},{"type":"WEB","url":"https://github.com/crewAIInc/crewAI/pull/6331"},{"type":"WEB","url":"https://github.com/crewAIInc/crewAI/commit/5d4851eac797cafc45b726f65747fe2c9520fc42"},{"type":"PACKAGE","url":"https://github.com/crewAIInc/crewAI"},{"type":"WEB","url":"https://github.com/crewAIInc/crewAI/releases/tag/1.15.1"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/crewai-ssrf-filter-bypass-via-http-redirect-in-scrape-tools"},{"type":"PACKAGE","url":"https://pypi.org/project/crewai-tools"},{"type":"ADVISORY","url":"https://github.com/advisories/GHSA-mr4r-hcgx-8p4h"}],"affected":[{"package":{"name":"crewai-tools","ecosystem":"PyPI","purl":"pkg:pypi/crewai-tools"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.15.1"}]}],"versions":["0.0.1","0.0.10","0.0.11","0.0.12","0.0.14","0.0.15","0.0.16","0.0.2","0.0.3","0.0.5","0.0.6","0.0.7","0.0.9","0.1.0","0.1.1","0.1.2","0.1.3","0.1.4","0.1.5","0.1.6","0.1.7","0.12.0","0.12.1","0.13.0","0.13.1","0.13.2","0.13.4","0.14.0","0.17.0","0.2.0","0.2.1","0.2.2","0.2.3","0.2.4","0.2.5","0.2.6","0.25.0","0.25.1","0.25.2","0.25.3","0.25.4","0.25.5","0.25.6","0.25.7","0.25.8","0.3.0","0.32.0","0.32.1","0.33.0","0.36.0","0.37.0","0.38.0","0.38.1","0.4.0","0.4.1","0.4.25","0.4.26","0.4.3","0.4.4","0.4.5","0.4.6","0.4.7","0.4.8","0.40.0","0.40.1","0.42.0","0.42.2","0.43.0","0.44.0","0.45.0","0.46.0","0.47.0","0.47.1","0.48.0","0.49.0","0.51.0","0.51.1","0.55.0","0.58.0","0.59.0","0.60.0","0.62.0","0.62.1","0.62.2","0.62.3","0.65.0","0.69.0","0.71.0","0.73.0","0.73.1","0.74.0","0.74.1","0.75.0","0.76.0","0.8.0","0.8.3","1.0.0","1.0.0a1","1.0.0a2","1.0.0a3","1.0.0a4","1.0.0b1","1.0.0b2","1.0.0b3","1.1.0","1.10.0","1.10.0a1","1.10.1","1.10.1.dev20260307","1.10.1.dev20260309","1.10.1.dev20260310","1.10.1.dev20260311","1.10.1a0","1.10.1a1","1.10.1b0","1.10.1b1","1.10.2a1","1.10.2a1.dev20260312","1.10.2a1.dev20260313","1.10.2rc1","1.10.2rc2","1.10.2rc2.dev20260314","1.10.2rc2.dev20260315","1.11.0","1.11.0.dev20260319","1.11.0.dev20260320","1.11.0.dev20260321","1.11.0.dev20260323","1.11.0rc1","1.11.0rc1.dev20260316","1.11.0rc1.dev20260317","1.11.0rc2","1.11.0rc2.dev20260318","1.11.1","1.11.1.dev20260324","1.11.1.dev20260325","1.12.0","1.12.0a1","1.12.0a2","1.12.0a3","1.12.1","1.12.1.dev20260326","1.12.2","1.13.0","1.13.0.dev20260403","1.13.0.dev20260404","1.13.0.dev20260406","1.13.0a1","1.13.0a2","1.13.0a3","1.13.0a4","1.13.0a4.dev20260401","1.13.0a5","1.13.0a6","1.13.0a6.dev20260402","1.13.0a7","1.13.0rc1","1.13.0rc1.dev20260327","1.13.0rc1.dev20260328","1.13.0rc1.dev20260331","1.14.0","1.14.0.dev20260408","1.14.0a2","1.14.0a3","1.14.0a3.dev20260407","1.14.0a4","1.14.1","1.14.1rc1","1.14.2","1.14.2.dev20260418","1.14.2.dev20260420","1.14.2a1","1.14.2a1.dev20260409","1.14.2a1.dev20260410","1.14.2a2","1.14.2a2.dev20260411","1.14.2a2.dev20260413","1.14.2a3","1.14.2a3.dev20260414","1.14.2a4","1.14.2a4.dev20260415","1.14.2a5","1.14.2rc1","1.14.2rc1.dev20260416","1.14.2rc1.dev20260417","1.14.3","1.14.3.dev20260425","1.14.3.dev20260428","1.14.3.dev20260429","1.14.3a1","1.14.3a1.dev20260421","1.14.3a2","1.14.3a2.dev20260422","1.14.3a3","1.14.3a3.dev20260423","1.14.3a3.dev20260424","1.14.4","1.14.4.dev20260501","1.14.4a1","1.14.4a1.dev20260430","1.14.5","1.14.5.dev20260519","1.14.5.dev20260520","1.14.5a1","1.14.5a1.dev20260502","1.14.5a1.dev20260503","1.14.5a1.dev20260504","1.14.5a2","1.14.5a2.dev20260505","1.14.5a3","1.14.5a3.dev20260507","1.14.5a3.dev20260508","1.14.5a4","1.14.5a4.dev20260509","1.14.5a4.dev20260512","1.14.5a5","1.14.5a5.dev20260513","1.14.5a5.dev20260514","1.14.5a6","1.14.5a6.dev20260516","1.14.5a7","1.14.6","1.14.6.dev20260529","1.14.6.dev20260530","1.14.6.dev20260601","1.14.6.dev20260602","1.14.6.dev20260603","1.14.6a1","1.14.6a1.dev20260521","1.14.6a1.dev20260522","1.14.6a1.dev20260523","1.14.6a1.dev20260526","1.14.6a1.dev20260527","1.14.6a2","1.14.6a2.dev20260528","1.14.7","1.14.7.dev20260612","1.14.7.dev20260613","1.14.7.dev20260614","1.14.7.dev20260615","1.14.7.dev20260616","1.14.7.dev20260617","1.14.7a1","1.14.7a1.dev20260604","1.14.7a1.dev20260605","1.14.7a2","1.14.7a2.dev20260606","1.14.7a3","1.14.7a3.dev20260609","1.14.7a4","1.14.7a4.dev20260610","1.14.7rc1","1.14.7rc2","1.14.7rc2.dev20260611","1.14.8a0","1.14.8a0.dev20260618","1.14.8a1","1.14.8a2","1.14.8a2.dev20260619","1.14.8a2.dev20260620","1.14.8a2.dev20260623","1.14.8a3","1.14.8a3.dev20260624","1.14.8a4","1.14.8a5","1.14.8a5.dev20260625","1.15.0","1.15.0.dev20260626","1.15.1.dev20260627","1.15.1.dev20260628","1.15.1.dev20260630","1.15.1a1","1.2.0","1.2.1","1.3.0","1.4.0","1.4.1","1.5.0","1.6.0","1.6.1","1.7.0","1.7.1","1.7.2","1.8.0","1.8.1","1.9.0","1.9.1","1.9.2","1.9.3"],"
