Description

HFS2 version 2.4.0 and earlier contains a template injection vulnerability in the multipart upload handler that allows unauthenticated attackers to achieve remote code execution by embedding malicious template syntax in a filename. Attackers can craft a filename containing a closing template quoting sequence followed by an exec macro, which bypasses the authorization check in the dispatcher to execute arbitrary commands on the underlying host system.

CVE-2026-97149

In OpenStack Swift before 2.38.2, the tempurl middleware does not reject the X-Copy-From header on PUT requests. A TempURL signature only covers the method, expiry, and path, and thus the list of disallowed headers is the only defense against a signed PUT request changing what the request does. An attacker holding a PUT TempURL for a single object can add an X-Copy-From header naming any object in the same account; the copy middleware copies that object to the destination, and the attacker then reads the victim's data back with a GET TempURL for the destination object. Copies across account boundaries are rejected. Only deployments using the shipped default proxy pipeline (tempurl and copy middleware) with account-level TempURL keys are affected.

CVE-2026-97151

mammoth (aka mammoth.js) before 1.12.2 is vulnerable to prototype pollution when reading the styles defined in a document. Converting a crafted .docx file allows an attacker to add arbitrary properties to Object.prototype. In 1.11.0 through 1.12.1, applications that convert further documents in the same process and return the converted HTML can also disclose the contents of local server files (to the party supplying the documents) by setting externalFileAccess to true.
