CVE-2025-49088Network attack vector

Remote service abort via crafted calendar invite

Published Dec 25, 2025 · Updated Dec 25, 2025

Improper input validation in Pexip Infinity 32.0 through 37.1 allows remote attackers to abort the OTJ service with a crafted invite. The One Touch Join service processes attacker-controlled calendar invitation data for a Microsoft Teams SIP Guest Join rule and reaches an assertion that terminates the software. Exposure requires an OTJ profile linked to an endpoint group with an endpoint and the applicable processing rule, plus permission to email that room resource; successful exploitation interrupts OTJ availability.
