CVE-2026-53436

A flaw was found in Jenkins. The system improperly validates redirect URLs after login, specifically when they contain relative path segments such as ./ or ../. This vulnerability allows attackers to craft malicious URLs that appear legitimate, leading to successful phishing attacks against users...

Prototype Pollution

Overview org.webjars.npm:jodit is a Jodit is awesome and usefully wysiwyg editor with filebrowser Affected versions of this package are vulnerable to Prototype Pollution via the Jodit.modules.Helpers.set function. An attacker can inject unexpected properties into Object.prototype by supplying a...

GHSA-VPMM-X3FM-QR5C jodit: Prototype pollution in Jodit via Jodit.modules.Helpers.set()

Summary Jodit.modules.Helpers.setchain, value, obj walks the dot-separated chain, creating and following each path segment, without filtering prototype-mutating keys. A chain that begins with or contains proto, constructor, or prototype lets the final assignment reach and mutate Object.prototype...

Authorization Bypass

Spring Data REST is vulnerable to Authorization Bypass. The vulnerability is due to improper enforcement of write-access restrictions in the JSON Patch application/json-patch+json implementation, where intermediate path segments in multi-segment JSON Pointer expressions are not subjected to...
