Local privilege escalation in Unity Parsec for Windows (all builds through v2026-05-04.0) lets an unprivileged local user coerce an instance of parsecd.exe to run as NT AUTHORITY\SYSTEM while honoring a user-controlled AppData environment variable, allowing the attacker to redirect the privileged process to resources under their control and gain SYSTEM. The flaw is a CWE-648 misuse of privileged APIs; publicly available exploit code exists (a dedicated CVE GitHub repository and a researcher write-up), and it is fixed in Parsec for Windows 150-104a. It is not listed in CISA KEV and no EPSS score was supplied, so there is no evidence of widespread active exploitation.
Parsec is a cloud-based application for cryptographically secure file sharing. In versions on the 3.x branch prior to 3.6.0, `libparsec_crypto`, a component of the Parsec application, does not check for weak order point of Curve25519 when compiled with its RustCrypto backend. In practice this means an attacker in a man-in-the-middle position would be able to provide weak order points to both parties in the Diffie-Hellman exchange, resulting in a high probability to for both parties to obtain ...
Unity Parsec has a TOCTOU race condition that permits local attackers to escalate privileges to SYSTEM if Parsec was installed in "Per User" mode. Rated high severity (CVSS 7.0). No vendor patch available.
In the uncurl_ws_accept function in uncurl.c in uncurl before 0.07, as used in Parsec before 140-3, insufficient Origin header validation (accepting an arbitrary substring match) for WebSocket API. Rated high severity (CVSS 8.8), this vulnerability is remotely exploitable, no authentication required, low attack complexity. This Cross-Site Request Forgery (CSRF) vulnerability could allow attackers to trick authenticated users into performing unintended actions.
