Summary
A race condition exists in PaperCut MF when processing badge-swipe data from certain HP multifunction devices. Under specific network conditions, the server may incorrectly process fragmented data chunks, leading to the registration of a truncated badge ID string.
Risk Assessment
This vulnerability may lead to unauthorized user logins if the truncated string is transformed into a valid ID belonging to a different user in environments utilizing custom badge-ID post-processing scripts.
Recommendation
It is recommended to monitor and update the PaperCut MF server configuration and implement safeguards to prevent the processing of truncated badge IDs.

An unspecified vulnerability in the print release functionality in PaperCut MF before version 14.1 (Build 26983) may lead to unknown impact and remote attack vectors, related to embedded MFPs.
- CVE-2026-6418Medium
In the Shared Account Synchronization component of PaperCut MF (version 25.0.4), an authenticated user with administrative privileges can specify arbitrary local file paths due to lack of path validation. This allows enumeration of directory structures and unauthorized reading of sensitive configuration or system files, whose contents are then exposed in the account management interface.
Original NVD description (English source)
A race condition exists in PaperCut MF when processing badge-swipe data from certain HP multifunction devices. Under specific network conditions involving dropped packets and out-of-order sequence counters, the server may incorrectly process fragmented data chunks. If a sequence reset notification fails to reach the server, the server may reject the initial data chunk while erroneously accepting subsequent chunks before a connection reset completes. This leads to the registration of a truncated badge ID string. While this typically results in an authentication failure, the vulnerability is compounded in environments utilizing custom badge-ID post-processing scripts. In such configurations, the truncated string may be transformed into a valid ID belonging to a different user, leading to unauthorized session establishment (Incorrect User Login) on the device.
