CVE-2026-24772 is a critical vulnerability affecting OpenProject versions 17.0.0 through 17.0.1, stemming from improper validation of backend URLs within its real-time collaboration synchronization server. This flaw allows an attacker to decrypt intercepted authentication tokens, potentially gaining unauthorized access to OpenProject on a victim's behalf. With a CVSS score of 9.0 (Critical), it presents a significant risk due to its network attack vector, low attack complexity, and high impact on confidentiality, integrity, and availability. While no active exploitation, public exploit code, or significant community discussion has been observed, organizations using affected versions should apply the fix in 17.0.2 or disable the collaboration feature and hocuspocus container as a workaround.
