What is CVE-2026-42260?

Open-WebSearch, a multi-engine server for web search and content retrieval, has a vulnerability that affects its URL validation process. The issue arises in the methods isPublicHttpUrl and assertPublicHttpUrl, which fail to correctly handle bracketed IPv6 literals and do not resolve DNS queries properly. This flaw allows a malicious actor to exploit non-blind SSRF vulnerabilities, potentially exposing sensitive data returned in the response body. The issue affects versions released before 2.1.7 and has been addressed in the latest update.
