CVE-2026-71236 Grocy - Stored XSS via HTMLPurifier Output Double-Decode

Grocy's API request-body parser controllers/Api/BaseApiController.php, GetParsedAndFilteredRequestBody purifies incoming field values with HTMLPurifier, then manually reverses HTML-entity encoding of the resulting output by replacing , , and back to , and & immediately after purification...

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...

EUVD-2026-51438

The Frontend Admin by DynamiApps WordPress plugin before 3.29.9 decodes HTML entities in a submitted form field value after sanitizing it, which restores HTML tags that the sanitizer had neutralized. A double-encoded payload submitted by an unauthenticated visitor is therefore stored as a live ta...

PYSEC-2026-1641 mlflow vulnerable to Path Traversal

A path traversal vulnerability exists in the mlflow/mlflow repository, specifically within the artifact deletion functionality. Attackers can bypass path validation by exploiting the double decoding process in the deleteartifactmlflowartifacts handler and localfileuritopath function, allowing for...

Directory Traversal

SiYuan is vulnerable to Directory Traversal. The vulnerability is due to improper handling of double URL decoding in the serveExport function, which allows an attacker to use double-encoded traversal sequences to read arbitrary files from the workspace...

GHSA-HJH7-R5W8-5872 SiYuan: Path Traversal via Double URL Encoding in `/export/` Endpoint (Incomplete Fix Bypass for CVE-2026-30869)

Summary The fix for CVE-2026-30869 in SiYuan v3.5.10 only added a denylist check IsSensitivePath but did not address the root cause — a redundant url.PathUnescape call in serveExport. An authenticated attacker can use double URL encoding %252e%252e to traverse directories and read arbitrary...

h3: Double Decoding in `serveStatic` Bypasses `resolveDotSegments` Path Traversal Protection via `%252e%252e`

Summary The serveStatic utility in h3 applies a redundant decodeURI call to the request pathname after H3Event has already performed percent-decoding with %25 preservation. This double decoding converts %252e%252e into %2e%2e, which bypasses resolveDotSegments since it checks for literal...

CVE-2024-1560

CVE-2024-1560 affects mlflow/mlflow prior to 2.9.2, in the artifact deletion path. A double decoding flaw in _delete_artifact_mlflow_artifacts and local_file_uri_to_path, via an extra unquote in delete_artifacts, allows path traversal and deletion of arbitrary server directories. Impact: high, wi...

SUSE CVE-2016-5099

Cross-site scripting XSS vulnerability in phpMyAdmin 4.4.x before 4.4.15.6 and 4.6.x before 4.6.2 allows remote attackers to inject arbitrary web script or HTML via special characters that are mishandled during double URL decoding...
