EEF-CVE-2026-115700 SSRF allowlist bypass via percent-encoded bracketed IPv6 or trailing-dot IP literal in hackney
Summary Interpretation Conflict vulnerability in hackneyurl in benoitc hackney allows Server Side Request Forgery via a percent-encoded bracketed IPv6 literal or an IP literal with a trailing dot. A host such as %5B%3A%3Affff%3A127%2E0%2E0%2E1%5D decoding to ::ffff:127.0.0.1 or 127.0.0.1. is not ...

CVE-2026-115700
The benoitc hackney library (versions 4.0.1 to 4.8.x ) is vulnerable to Server-Side Request Forgery (SSRF) due to an Interpretation Conflict in hackney_url. Specifically, the hackney_url:normalize/2 function fails to block percent-encoded bracketed IPv6 literals (e.g., %5B%3A%3Affff%3A127%2E0%2E0...
CVE-2026-55190 Event Schedule Vulnerable to SSRF: isUrlSafe() bypassable via bracketed IPv6 literals (parse_url keeps the brackets so the IPv6 guard never matches) and a v4-only-resolver fail-open; reaches internal/localhost services on event import
Event Schedule is an open-source platform to share events, sell tickets and bring communities together. In versions 1.0.0 and prior, App\Utils\UrlUtils::isUrlSafe is the SSRF guard applied to user-supplied import URLs. It can be bypassed two ways, both reaching internal/localhost services when th...

PT-2026-82065
mcp-fetch checks a fetch target against its SSRF guard without removing the brackets that surround an IPv6 literal. isSafeUrl reads the hostname from the parsed URL, which for a literal such as http://::1/ yields the bracketed string, and then tests it with net.isIP. That call returns zero for a...
CVE-2026-42260 Open-WebSearch: SSRF in `fetchWebContent` MCP tool: bracketed IPv6 literals and non-resolving hostname check bypass `isPrivateOrLocalHostname`
Open-WebSearch is a multi-engine MCP server, CLI, and local daemon for agent web search and content retrieval. Prior to 2.1.7, isPublicHttpUrl / assertPublicHttpUrl in src/utils/urlSafety.ts do not recognize bracketed IPv6 literals and do not resolve DNS, which combine to allow non-blind SSRF wit...
CVE-2026-42260
Open-WebSearch CVE-2026-42260 describes a SSRF in fetchWebContent of the MCP tool where bracketed IPv6 literals and lack of DNS resolution allow bypassing the public URL checks. The vulnerability arises because isPublicHttpUrl / assertPublicHttpUrl in src/utils/urlSafety.ts treat bracketed IPv6 h...
GHSA-V228-72C7-FX8J open-websearch has SSRF in `fetchWebContent` MCP tool: bracketed IPv6 literals and non-resolving hostname check bypass `isPrivateOrLocalHostname`
Summary src/utils/urlSafety.ts exposes isPublicHttpUrl / assertPublicHttpUrl, used to gate the MCP fetchWebContent tool against private-network targets. The check has two defects that together allow non-blind SSRF with the response body returned to the caller: 1. Bracketed IPv6 literals are never...
Amazon Linux 2 : runc, --advisory ALAS2NITRO-ENCLAVES-2025-072 (ALASNITRO-ENCLAVES-2025-072)
The version of runc installed on the remote host is prior to 1.3.2-2. It is, therefore, affected by a vulnerability as referenced in the ALAS2NITRO-ENCLAVES-2025-072 advisory. Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version...

CVE-2025-47912 Insufficient validation of bracketed IPv6 hostnames in net/url
The Parse function permits values other than IPv6 addresses to be included in square brackets within the host component of a URL. RFC 3986 permits IPv6 addresses to be included within the host component, enclosed within square brackets. For example: "http://::1/". IPv4 addresses and hostnames mus...
