Hub

Resource exhaustion DoS in @anephenix/hub (npm) before 0.2.16 allows any unauthenticated remote client to exhaust server CPU and memory by opening WebSocket connections and ignoring all server RPC messages. Each connection triggers a 10ms setInterval polling loop and a heap entry in the RPC request queue; because the socket close handler never cancels these allocations, they accumulate without bound until the process becomes unresponsive. No active exploitation is confirmed (not in CISA KEV); vendor-released patch is available in v0.2.16.

Privileged GITHUB_TOKEN exfiltration in the meltano/hub repository allows any unauthenticated attacker who can open a pull request to inject shell commands into the test_dispatcher.yml GitHub Actions workflow and steal a repository-write token. Because the workflow uses the pull_request_target trigger, it executes untrusted PR-controlled data (changed filenames) in the trusted base-repository context with access to secrets. Publicly available exploit code exists (a dedicated PoC repo), though this is not listed in CISA KEV.

Authentication bypass in JetBrains Hub (the identity and account-management server behind TeamCity, YouTrack, and other JetBrains tools) lets an actor obtain administrative access by going through direct database access, per JetBrains' own advisory. Classified under CWE-306 (Missing Authentication for a Critical Function) and vendor-scored CVSS 9.8, it affects all builds before the fixed 2026.1.13757, 2025.3.148033, 2025.2.148048, 2025.1.148120, 2024.3.148430, and 2024.2.148429 releases. There is no public exploit identified at time of analysis and the EPSS probability is low (0.44%, 35th percentile), but full administrative compromise is the stated technical impact.

Privilege escalation in JetBrains Hub (versions prior to 2026.1.13757, 2025.3.148033, 2025.2.148048, 2025.1.148120, 2024.3.148430, and 2024.2.148429) allows an authenticated attacker to attach additional authentication details to existing accounts, enabling unauthorized access and elevation of privileges. The flaw, self-reported by JetBrains and patched, carries a CVSS 8.8 with high impact to confidentiality, integrity, and availability; no public exploit is identified at time of analysis and EPSS exploitation probability is low (0.41%).

Account takeover in JetBrains Hub is possible through predictable restore codes, affecting all versions prior to 2026.1.13757, 2025.3.148033, 2025.2.148048, 2025.1.148120, 2024.3.148430, and 2024.2.148429. Remote unauthenticated attackers can guess or predict the restore codes used for account recovery, enabling them to seize control of arbitrary user accounts. No public exploit identified at time of analysis, but the CVSS 9.8 rating reflects the high impact of full account compromise across an identity management platform.

JetBrains Hub versions prior to 2026.1 contain an authentication bypass vulnerability where attackers with valid credentials can gain unauthorized access to accounts through sign-in mismatches when SSO is disabled and two-factor authentication is not configured. An authenticated attacker can exploit this to achieve both confidentiality and integrity violations. No patch is currently available for this vulnerability.
