CVE-2026-118697
CriticalCVSS 9.0Summary
In JetBrains Toolbox App before 3.9.1 and 3.8.2, and IntelliJ IDEA before 2026.3 and 2026.2.4, the jetbrainsd daemon trusted compromised intermediate certificates. This may allow an attacker to impersonate a trusted component.
Risk Assessment
Organizations using these JetBrains tools may be exposed to trust compromise in daemon communication, potentially enabling man-in-the-middle attacks.
Recommendation
Update JetBrains Toolbox App to version 3.9.1 or 3.8.2 and IntelliJ IDEA to version 2026.3 or 2026.2.4.

Prior to 1.5.7-beta.14, the `api_ns_plex` namespace in `bazarr/api/plex/oauth.py` omits `@authenticate` on its Resource handlers, allowing anonymous callers to perform configuration-mutating operations such as logging out the Plex integration, persisting an attacker-selected API key, binding an attacker-controlled Plex account token, and other `write_config()` operations. Missing OAuth state validation and attacker-controlled server URLs further enable server-side request forgery and credential exposure.
- CVE-2026-112816Critical
Improper certificate validation in the HTTPS listener in Canonical LXD 4.0.14, 5.0.10, 5.21.8, 6.9 before 4.0.15, 5.0.11, 5.21.9, 6.10.1 allows an unauthenticated attacker to authenticate as any trusted client and gain full access to the cluster and managed virtual machines via a crafted certificate chain.
- CVE-2026-119706Critical
InternLM LMDeploy 0.9.0 through 0.18.0 contains an unauthenticated remote code execution vulnerability. Attackers can send a base64-encoded crafted pickle in serialized_named_tensors to the /update_weights endpoint, which ForkingPickler.loads deserializes without validation, executing commands as the api_server process.
- CVE-2026-93327Critical
A deserialization of untrusted data vulnerability in the SubWorkflow task in Google Cloud Application Integration versions prior to 2026-09-11 allows an authenticated attacker to execute arbitrary code using a maliciously crafted serialized object. The vulnerability was patched on 11 September 2026.
