Local privilege escalation in certain Zoom Clients for Windows lets an authenticated local user exploit a time-of-check to time-of-use (TOCTOU) race during install/uninstall to gain higher privileges (likely SYSTEM). The flaw was reported by Zoom's own security team and is documented in bulletin ZSB-26012; no public exploit identified at time of analysis and it is not on CISA KEV. The high-complexity race window and local-access requirement temper an otherwise high-impact (C:H/I:H/A:H) issue.
Local privilege escalation in Zoom Rooms for Windows before version 7.1.0 allows an authenticated low-privileged user to elevate to higher privileges via local access, with high impact to confidentiality, integrity, and availability (CVSS 7.8). Zoom's own security team (security@zoom.us) reported the flaw, classified as improper privilege management. No public exploit identified at time of analysis, and it is not listed in CISA KEV.
Zoom Client for Windows contains a privilege escalation vulnerability that allows authenticated local users to gain elevated system privileges through improper access controls. An attacker with valid credentials can exploit this weakness to execute arbitrary code or access sensitive system resources without administrative approval. No patch is currently available for this issue.
Improper Input Validation in Zoom Room versions up to 6.6.5 is affected by improper input validation (CVSS 7.0).
Local information disclosure in Zoom Rooms for macOS before version 6.6.0 allows an authenticated local user to exploit external control of a file name or path, potentially reading arbitrary files accessible to the Zoom Rooms process. The vulnerability requires an existing authenticated session on the host (PR:L) and cannot be triggered remotely or without authentication. With a CVSS base score of 5.5 and an EPSS score of 0.14%, it poses a low-priority risk; no public exploit code or active exploitation has been identified at time of analysis.
Local privilege escalation in Zoom Rooms for Windows before 6.6.0 allows an attacker with local access and low-level privileges (PR:L per CVSS vector) to bypass downgrade protection and install an older, vulnerable client build, escalating privileges. This protection mechanism failure (CWE-693) is a local, lower-urgency issue; no public exploit code or active exploitation has been identified at time of analysis, and EPSS is low at 0.16%.
External control of file name or path in certain Zoom Clients may allow an unauthenticated user to conduct a disclosure of information via network access. Rated medium severity (CVSS 4.3), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.
Improper removal of sensitive information in certain Zoom Clients before version 6.5.10 may allow an unauthenticated user to conduct a disclosure of information via network access. Rated medium severity (CVSS 5.3), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.
Zoom Rooms Clients prior to version 6.5.1 contain an authentication bypass (CWE-288) that lets a remote, unauthenticated attacker reach an alternate code path and disclose information without supplying valid credentials. The flaw carries a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N), meaning no privileges, no user interaction, and no special configuration are required - only network reachability to an affected client - while confidentiality impact is rated High and integrity/availability are unaffected. Exploitation is not confirmed in the wild: no public exploit code has been identified at time of analysis, and EPSS is a low 0.28% (19th percentile), so this is a moderate, patch-on-schedule issue rather than an emergency. Zoom released version 6.5.1 as the fix.
Command injection in Zoom clients for Windows allows an authenticated user with network access to trigger a disclosure of information from a vulnerable client, affecting Zoom Workplace Desktop, the Zoom Meeting SDK, Zoom Rooms, and Zoom Workplace VDI. Exploitation requires a valid authenticated session (CVSS PR:L) but no user interaction (UI:N), and the assessed impact is confined to confidentiality (C:H) with no integrity or availability effect. There is no public exploit identified at time of analysis, no confirmed active exploitation (CISA KEV), and EPSS is 1.82% (78th percentile) - a moderate-priority issue rather than a top-tier emergency.
