JetBrains released fixes for two security vulnerabilities affecting IntelliJ IDEA and TeamCity, including CVE-2026-59792, a path traversal flaw in IntelliJ IDEA that can lead to remote code execution. The issue stems from project workspace ID handling and affects versions before 2026.1.4 and 2026.2. The vulnerability is classified as CWE-23 and carries a high-severity CVSS 9.6 rating, with potential for significant confidentiality and integrity impact.
JetBrains also patched CVE-2026-59794, a stored cross-site scripting flaw in TeamCity caused by unsanitized agent-reported data on the cloud profile page. That issue affects versions before 2026.1.2 and is rated high severity. Public reporting said no in-the-wild exploitation had been confirmed at the time of disclosure, but the flaws pose risk to developer endpoints and CI/CD environments, prompting organizations using the affected products to update to the fixed releases published on JetBrains' security advisories page.

JetBrains released fixes for **18 vulnerabilities** affecting multiple developer products, including **IntelliJ IDEA, TeamCity, WebStorm, PhpStorm, PyCharm, and GoLand**, with the most severe issues concentrated in IntelliJ IDEA Remote Development and TeamCity. Two IntelliJ IDEA flaws, **`CVE-2026-64812`** and **`CVE-2026-64813`**, were rated **CVSS 10.0** and could allow unauthorized input injection and unauthorized settings modification during Remote Development sessions in versions before **2026.2**. JetBrains also fixed **`CVE-2026-64814`**, which exposed unauthorized file access in Remote Development, and **`CVE-2026-64815`**, an arbitrary code injection issue via UI Designer form files. Several IDE vulnerabilities could be triggered **before project trust was granted**, allowing arbitrary code execution through project-local tooling or configured interpreters in **WebStorm** (`CVE-2026-64804`, `CVE-2026-64805`, `CVE-2026-64806`), **PhpStorm** (`CVE-2026-64808`, `CVE-2026-64809`), and **PyCharm** (`CVE-2026-65908`). **TeamCity** received fixes for **`CVE-2026-65907`**, a **CVSS 9.1** remote code execution flaw in Git VCS roots, and **`CVE-2026-65906`**, a Kotlin DSL sandbox escape affecting versions before **2026.1.2** and **2025.11.6**. The Canadian Centre for Cyber Security urged administrators to apply JetBrains’ updates, and available reporting said there was **no confirmed in-the-wild exploitation or public proof-of-concept** at the time of disclosure.

JetBrains has patched a high-severity vulnerability in TeamCity On-Premises, tracked as **`CVE-2026-44413`**, that can allow privilege escalation and expose parts of the TeamCity server API to unauthorized users. The company said affected deployments include TeamCity On-Premises **2025.11.4 and earlier**, and advised customers to upgrade to **TeamCity 2026.1** or apply the available security patch plugin. According to JetBrains, the flaw could expose sensitive data including API tokens, Git credentials, build secrets, logs, and user information, with higher risk in environments that permit inbound connections on non-standard ports or run build agents on the same host as the TeamCity server. The issue requires access to a TeamCity account, which attackers could obtain through brute force, credential stuffing, leaked credentials, social engineering, or enabled guest access, raising the prospect of follow-on compromise of cloud infrastructure, source code repositories, and software delivery pipelines. The disclosure comes against a backdrop of repeated TeamCity security incidents, including **`CVE-2024-27198`** and **`CVE-2024-27199`**, two critical flaws that allowed unauthenticated attackers to bypass authentication, take over servers, alter certificates and ports, and create supply-chain attack paths; those earlier bugs were fixed in **2023.11.4** after researchers warned they could lead to full server compromise.

Atlassian disclosed a critical Confluence vulnerability, **`CVE-2023-22515`**, that can let an attacker create unauthorized administrator accounts and potentially take over the entire environment. Atlassian assessed the flaw as likely falling between **9.0 and 10.0** in severity and urged defenders to restrict access to the vulnerable component until patches could be applied. Authorities warned that any internet-exposed vulnerable instance showing even minor anomalies should be treated as potentially compromised, with indicators including unexpected additions to the `confluence-administrators` group, unexplained user creation, requests to `/setup/*.action`, and evidence of `/setup/setupadministrator.action` in `atlassian-confluence-security.log`. Subsequent analysis indicated the flaw might also be exploitable without creating an administrator account, including through `/server-info.action`, and Microsoft reported signs of exploitation dating back to mid-September 2023. JetBrains later released fixes for critical TeamCity authentication bypass vulnerabilities affecting all on-premises server installations through version **`2023.11.3`**, resolving them in **`2023.11.4`**. The company said an unauthenticated attacker could send specially crafted HTTP(S) requests to bypass authentication or gain administrator-level access, and exploitation attempts had already been observed. JetBrains updated and checked its cloud-hosted service, while defenders running on-premises TeamCity were told to patch immediately and review systems for compromise after updating, underscoring the ongoing risk from exposed enterprise collaboration and CI/CD platforms that can be seized through admin-level access flaws.
