Prior to version 4.6.40 of PraisonAI, corresponding to version 1.6.40 of praisonaiagents, `spider_tools` URL validation can be bypassed using alternate loopback host encodings. The tool contains a URL validation function intended to block local or unsafe targets before fetching attacker-controlled URLs. However, the validation only blocks a small set of exact host strings such as `localhost` and `127.0.0.1`. It does not normalize hostnames, resolve DNS, parse numeric IPv4 variants, or validate the final resolved IP address before making the request. As a result, certain URLs may bypass the protection and still reach loopback services. After the weak validation passes, `scrape_page()` calls `requests.Session.get()` on the attacker-controlled URL. This allows an attacker who can influence URLs passed to `scrape_page`, `crawl`, or `extract_text` to induce SSRF requests against loopback-only services. This is a server-side request forgery protection bypass. PraisonAI version 4.6.40 and praisonaiagents version 1.6.40 contain a patch.","published_at":"2026-07-21T14:47:53.059000Z","last_modified_at":"2026-07-22T15:17:17.097000Z","cvss_v3_score":5.5,"cvss_v3_vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N","cvss_v3_severity":"MEDIUM","cvss_v4_score":null,"cvss_v4_vector":null,"cvss_v4_severity":null,"ssvc_decision":null,"ssvc_exploitation":"poc","ssvc_automatable":false,"ssvc_technical_impact":"partial","cwes":["CWE-918"],"nvd_references":["https://github.com/MervinPraison/PraisonAI/security/advisories/GHSA-5c6w-wwfq-7qqm","https://github.com/MervinPraison/PraisonAI/pull/1684","https://github.com/MervinPraison/PraisonAI/commit/b0d8f777528f3253a0cfb0a3ef65455da6ae32f6"],"vuln_status":"Deferred","trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-07-21T16:40:10.179167Z","updated_at":"2026-07-22T22:41:08.814983Z"},"effective_severity":"MEDIUM","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":"3.1","metrics":[{"metric":"AV","name":"Attack Vector","value":"L","value_label":"Local"},{"metric":"AC","name":"Attack Complexity","value":"L","value_label":"Low"},{"metric":"PR","name":"Privileges Required","value":"N","value_label":"None"},{"metric":"UI","name":"User Interaction","value":"R","value_label":"Required"},{"metric":"S","name":"Scope","value":"U","value_label":"Unchanged"},{"metric":"C","name":"Confidentiality","value":"H","value_label":"High"},{"metric":"I","name":"Integrity","value":"N","value_label":"None"},{"metric":"A","name":"Availability","value":"N","value_label":"None"}]},"cvss_v4_decoded":{"version":null,"metrics":[]},"affected":[{"vendor_slug":"mervinpraison","vendor_name":"MervinPraison","product_slug":"praisonai","product_name":"PraisonAI","version_start":"< 4.6.40","version_start_inclusive":true,"version_end":"< 4.6.40","version_end_inclusive":true,"cpe23_uri":"cve5:mervinpraison:praisonai:< 4.6.40:< 4.6.40"},{"vendor_slug":"mervinpraison","vendor_name":"MervinPraison","product_slug":"praisonaiagents","product_name":"praisonaiagents","version_start":"< 1.6.40","version_start_inclusive":true,"version_end":"< 1.6.40","version_end_inclusive":true,"cpe23_uri":"cve5:mervinpraison:praisonaiagents:< 1.6.40:< 1.6.40"}],"exploit_refs":[],"news":[],"references":[{"url":"https://github.com/MervinPraison/PraisonAI/security/advisories/GHSA-5c6w-wwfq-7qqm","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://github.com/MervinPraison/PraisonAI/pull/1684","source_type":"PATCH","tags":["patch"]},{"url":"https://github.com/MervinPraison/PraisonAI/commit/b0d8f777528f3253a0cfb0a3ef65455da6ae32f6","source_type":"PATCH","tags":["patch"]}],"timeline":[{"type":"published","at":"2026-07-21T14:47:53.059000Z","label":"CVE published","source":null},{"type":"ssvc_changed","at":"2026-07-22T14:46:53.964720Z","label":"SSVC decision revised","source":"vulnrichment"},{"type":"ssvc_changed","at":"2026-07-22T14:46:53.964720Z","label":"SSVC decision revised","source":"vulnrichment"},{"type":"ssvc_changed","at":"2026-07-22T14:46:53.964720Z","label":"SSVC decision revised","source":"vulnrichment"}]}
