Detects DNS rebinding vulnerability that allows bypass of SSRF protection. The vulnerability exists in the URL validation mechanism where DNS resolution is performed without considering DNS rebinding attacks. id: CVE-2024-24759 info: name: MindsDB -DNS Rebinding SSRF Protection Bypass author: Lee...

CVE-2026-55524 PraisonAI: SSRF in web_crawl tool via redirect-following and DNS rebinding (validate-then-fetch gap)

PraisonAI is a multi-agent teams system. In versions prior to 1.6.58, the webcrawl tool performs its SSRF check only on the initially supplied URL, allowing the protection to be bypassed so the tool connects to attacker-chosen internal destinations. The check resolves the hostname once with...

CVE-2026-55524

PraxionAI’s web_crawl tool is affected by an SSRF in versions prior to 1.6.58. The vulnerability arises because the tool validates the hostname only at initial resolution, then re-resolves at connect time in the fetch path (httpx Client with follow_redirects enabled or urllib), bypassing the init...

CVE-2026-71272

Memos' webhook dispatch function safeDialContext internal/webhook/webhook.go resolves the target hostname via net.DefaultResolver.LookupHost and validates the resulting IPs against reserved ranges, but then dials net.JoinHostPorthost, port using the original hostname rather than the...

CVE-2026-71250

Firefly III is reported vulnerable due to IsValidWebhookUrl.php: the validator explicitly allows any address in 127.0.0.0/8, enabling an authenticated user with webhooks enabled to configure a webhook targeting loopback services on the server. Furthermore, the validator resolves the target once v...

CVE-2026-54020

Open WebUI (self-hosted AI platform) contains a DNS rebinding SSRF vulnerability (CVE-2026-54020) affecting pre-0.11.0 behavior. An attacker who controls authoritative DNS for a submitted hostname could have validation return a public address while the connection later resolves to an internal add...

CVE-2026-54020 Open WebUI: DNS Rebinding SSRF Bypass

Open WebUI is an extensible, feature-rich, and user-friendly self-hosted AI platform. Prior to 0.11.0, Open WebUI resolved a hostname during URL validation and rejected private, loopback, and link-local addresses, but the HTTP clients resolved the hostname again at connection time. An authenticat...
