CVE-2026-78207 exceljs through 4.4.0 Prototype Pollution via deepMerge Reached From Note Serialization

exceljs through 4.4.0 contains a prototype pollution vulnerability in the deepMerge helper that fails to reject proto, constructor, or prototype keys when merging note objects. Attackers can assign parsed JSON with a malicious proto property to cell notes, modifying Object.prototype and affecting...

dompurify: DOMPurify: Cross-site scripting via permanent attribute allowlist pollution

A flaw was found in DOMPurify. When the setConfig function is used with an uponSanitizeAttribute hook, the ALLOWEDATTR allowlist is not properly cloned. This allows an attacker to register a hook that can permanently modify the shared allowlist, enabling the conditional allowance of dangerous...

dompurify: DOMPurify: Cross-Site Scripting (XSS) via prototype pollution in USE_PROFILES mode

A flaw was found in DOMPurify. This prototype pollution vulnerability, specifically when operating in USEPROFILES mode, allows a remote attacker to bypass attribute filtering. By manipulating Array.prototype properties, an attacker can cause DOMPurify to accept event handlers as allowed attribute...

SUSE CVE-2026-74866

@fastify/busboy is a multipart form-data parser for Node.js. Its multipart part-header parser splits header lines only on the two-byte carriage-return line-feed sequence, so a lone carriage return or line feed embedded in a part header is not treated as a line break and is carried verbatim into t...

CVE-2026-77414

JSONata is a JSON query and transformation language. Prior to 1.8.8 and 2.2.1, the src/jsonata.js environment.lookup function used a bypassable hasOwnProperty check. Crafted expressions could use $hasOwnProperty, $spread, $string, prototype access, and $constructor to reach the object prototype a...

CVE-2026-77415

JSONata (a JSON query and transformation language) is vulnerable to arbitrary code execution in versions prior to 1.8.8 and 2.2.1 . An attacker can craft JSONata expressions that chain multiple object-integrity weaknesses—overwriting $clone, exposing internal functions via $merge.*, replacing pro...
