JetBrains patched a critical flaw in TeamCity, its continuous integration and delivery server, that lets an unauthenticated attacker run operating-system commands. Tracked as CVE-2026-63077 and scored 9.8, the deserialization bug affects all on-premises versions and is reached through the agent polling protocol, letting an attacker with HTTP access bypass authentication and execute commands with the privileges of the server process. JetBrains warns that exploitation exposes stored credentials and can compromise the integrity of the build pipeline. It is fixed in versions 2025.11.7 and 2026.1.3, with a patch plugin for older releases, and TeamCity Cloud is already updated. No exploitation has been reported.
Aikido Security uncovered a coordinated campaign of at least 15 malicious plugins on the JetBrains Marketplace that pose as AI coding assistants but secretly steal the AI provider API keys developers enter. The plugins offer real features like chat, code review, and commit messages, so they work as advertised, but the moment a user pastes in an OpenAI, DeepSeek, or SiliconFlow key and clicks Apply, the key is silently sent to an attacker server over plain HTTP, with no prompt. The campaign has run since late October 2025, with new plugins as recent as June 10, and uses inflated downloads and fake reviews. Separately, malicious Chrome extensions were found capturing chatbot conversations.
CISA added eight actively-exploited vulnerabilities to its Known Exploited Vulnerabilities catalog on April 20, with federal agencies required to patch three Cisco Catalyst SD-WAN Manager flaws by today, April 23, and the remaining five by May 4. The Cisco trio (CVE-2026-20122, CVE-2026-20128, CVE-2026-20133) enable arbitrary file upload with vmanage user privileges, recovery of stored credentials for the DCA user, and unauthenticated disclosure of sensitive configuration data. Cisco confirmed exploitation of the first two in March 2026. The other five cover a wide blast radius: CVE-2025-32975 is a CVSS 10.0 authentication bypass in Quest KACE Systems Management Appliance letting attackers impersonate any user without credentials, exploited in the wild by unknown actors last month per Arctic Wolf. CVE-2023-27351 is the PaperCut NG/MF bypass that Microsoft's Lace Tempest chained into Cl0p and LockBit deployments back in 2023. CVE-2024-27199 is a path traversal in JetBrains TeamCity giving limited admin actions - its sibling CVE-2024-27198 is already on the KEV list. CVE-2025-48700 is a Zimbra XSS that the Ukrainian CERT attributes to UAC-0233/UAC-0250 for stealing mailbox contents, MFA backup codes, and application passwords. CVE-2025-2749 is a Kentico Xperience Staging Sync Server path traversal.
