EUVD-2026-4937

PolarLearn is a free and open-source learning program. Prior to version 0-PRERELEASE-15, the vote API route POST /api/v1/forum/vote trusts the JSON body’s direction value without runtime validation. TypeScript types are not enforced at runtime, so an attacker can send arbitrary strings e.g., "x" ...

CVE-2026-25126

PolarLearn prior to version 0-PRERELEASE-15 is vulnerable in the vote API at POST /api/v1/forum/vote, where the request body field direction is not validated at runtime. This allows sending arbitrary strings; downstream VoteServer treats any non-up and non-null value as a downvote and stores the ...

kernel: USB: usbtmc: Fix direction for 0-length ioctl control messages

A flaw was found in the Linux kernel’s USB Test and Measurement Class usbtmc driver. The driver did not properly validate the direction bit when handling ioctl calls for control messages with a length of zero. Under these circumstances, an incorrect direction can be submitted, leading to mismatch...
