CVE-2026-86251

h3 versions before 1.15.9 contain a path traversal vulnerability in the serveStatic utility. A double-decoding flaw allows a request path containing double-encoded dot sequences e.g. %252e%252e to be decoded to %2e%2e, which survives resolveDotSegments because that function only checks for litera...

CVE-2026-86251

Versions of h3 before 1.15.9 contain a path traversal vulnerability in the serveStatic utility. The root cause is a double-decoding flaw : a request path containing double-encoded dot sequences (e.g. %252e%252e) decodes to %2e%2e, which survives the resolveDotSegments() function because it only c...

fast-uri: fast-uri: Server-Side Request Forgery via repeated hostname percent-decoding

A flaw was found in fast-uri, a URI parser for Node.js. The component incorrectly decodes percent escapes in a hostname twice during URI parsing and authority recomposition. This double decoding can allow a remote attacker to manipulate a URI to point to a different network destination, such as a...

Linux Distros Unpatched Vulnerability : CVE-2026-75899

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - fast-uri is a URI parser for Node.js. It decodes percent escapes in a hostname during parsing and then decodes the parsed hostname a second time during authorit...

Double Decoding of the Same Data

Overview fast-uri is a Dependency-free RFC 3986 URI toolbox Affected versions of this package are vulnerable to Double Decoding of the Same Data through hostname normalization in normalize and resolve and the authority recomposition logic in index.js and lib/utils.js. An attacker can redirect an...

CVE-2026-75899

fast-uri , a URI parser for Node.js, suffers from double percent-decoding of the hostname: it decodes percent escapes during parsing and decodes them again during authority recomposition. This violates RFC 3986 §2.4 (an implementation must not decode the same string more than once) and allows a s...

fast-uri is a URI parser for Node.js. It decodes percent escapes in a hostname during parsing and then decodes the parsed hostname a second time during authority recomposition, so a single call to normalize or resolve can turn nested percent-encoded input into a different network destination such...

CVE-2026-71236

Grocy is affected by CVE-2026-71236 due to a flaw in its API request-body parser: after HTMLPurifier cleans values, the code re-decodes certain HTML entities (<, >, &) to , and &, effectively reconstructing live HTML/script tags. This double-decoding reintroduces stored XSS in API-writa...
