GitLab Warns of Active Exploitation of Critical GraphQL Flaw
GitLab emergency-patches actively exploited flaw CVE-2026-19478 (CVSS 9.4), letting unauthenticated attackers modify or delete public projects on self-managed servers.
GitLab emergency-patched CVE-2026-19478 (CVSS 9.4) on August 17 after WatchTowr researchers warned of active exploitation. The flaw lets unauthenticated attackers remotely modify or delete public projects and user data through a GraphQL directive, affecting only self-managed installations. Fixes ship in versions 19.2.4, 19.1.6, 19.0.8, and 18.11.11; the 18.2-18.10 branches receive no patch and must upgrade. Until patching, defenders should restrict unauthenticated access to /api/graphql, disable public repositories, and hunt for @gl_introduced in logs.

GitLab Patches Critical Unauthenticated GraphQL Vulnerability
GitLab issued an emergency patch for a critical unauthenticated GraphQL flaw (CVE-2026-19478, CVSS 9.4) enabling remote modification or deletion of public projects.
GitLab patched CVE-2026-19478 (CVSS 9.4), an unauthenticated GraphQL directive flaw allowing remote modification or deletion of public projects and user data on self-managed servers. The emergency patch released August 17 covers versions 19.2.4, 19.1.6, 19.0.8, and 18.11.11, but no fixes exist for the 18.2-18.10 branches. A second issue, a CSRF weakness in GraphQL multiplex queries (CVE-2026-19650, CVSS 7.1), shipped in the same release. No exploitation or public PoC has been observed; the flaw was reported by hiimguardian through HackerOne.

Perfect-10 GitLab bug under attack days after patch lands
CISA confirms active exploitation of CVSS 10.0 GitLab path traversal flaw CVE-2026-85706 days after patches shipped, enabling unauthenticated arbitrary file reads.
CISA added CVE-2026-85706, a maximum-severity 10.0 CVSS path traversal flaw in GitLab's repository commits API, to its Known Exploited Vulnerabilities catalog and confirmed active exploitation. The bug allows unauthenticated attackers to read arbitrary files, including configuration data and credentials, from self-managed GitLab CE/EE servers via a single HTTP POST request. GitLab shipped fixes on September 10 in versions 19.3.2, 19.2.6, and 19.1.8, covering versions 18.7 through 19.3. watchTowr is observing probes against internet-facing instances and warns widespread exploitation is likely to follow quickly.

Three JFrog Artifactory Flaws Exploited for Backdoor Deployment
Wiz reports multiple actors chaining three JFrog Artifactory auth flaws to gain admin and deploy backdoors; CISA added all three CVEs to KEV.
Wz reports threat actors exploiting CVE-2026-42018, CVE-2026-42016, and CVE-2026-82329 in self-hosted JFrog Artifactory instances to bypass authentication and gain administrative privileges. Between August 15 and September 8, 2026, multiple actors chained CVE-2026-42018 and CVE-2026-42016 to mint anonymous-user tokens, escalate privileges, create persistent admin accounts, install malicious plugins for code execution, and drop second-stage payloads. From early September, CVE-2026-82329 was exploited for configuration exfiltration, cluster key theft, token minting, and SSH key attachment to attacker-created accounts. CISA added all three CVEs to its KEV catalog, giving federal agencies two weeks under BOD 26-04 to patch to versions 7.161.20, 7.146.38, 7.133.29, 7.125.20, 7.117.28, or 7.111.21.

Critical GitLab Flaws Let Attackers Read Arbitrary Files, Steal Credentials and Execute Code
GitLab issues emergency patches for critical path-traversal flaw CVE-2026-85706 (CVSS 10.0), GraphQL credential exposure CVE-2026-87719, and potential RCE flaw CVE-2026-88765.
GitLab released versions 19.3.2, 19.2.6, and 19.1.8 on September 10, 2026, fixing 18 vulnerabilities across Community and Enterprise Editions. CVE-2026-85706 allows unauthenticated arbitrary file reads via the repository commits API; CVE-2026-87719 exposes Advanced Search credentials through GraphQL subscription deserialization; CVE-2026-88765 may enable authenticated RCE via crafted project export imports. No exploitation was reported, but self-managed administrators are urged to upgrade immediately and review logs for suspicious API and GraphQL activity.

JFrog security advisory (AV26-867) – Update 1
CISA added actively exploited CVE-2026-82329 in JFrog Artifactory to its KEV catalog; administrators of affected versions should patch.
Canada's Cyber Centre (advisory AV26-867, Update 1) relays a JFrog security advisory covering Artifactory, where open-source reporting indicates CVE-2026-82329 is being exploited in the wild. CISA added the flaw to its Known Exploited Vulnerabilities catalog on September 2, 2026. Multiple Artifactory release lines prior to fixed versions (e.g., prior to 7.111.21 through 7.161.20) are affected; users and administrators are urged to apply available updates.

Attackers Exploit Critical JFrog Artifactory Flaw to Mint Admin Tokens Days After Disclosure
Threat actors exploit CVE-2026-82329, a default-config authentication bypass in JFrog Artifactory, to mint administrator tokens days after patch release.
watchTowr reports that CVE-2026-82329 (CVSS 9.8), an authentication bypass in JFrog Artifactory patched in version 7.161.20 on August 28, 2026, is being actively exploited as of September 1. The flaw, in JFrog Access, lets unauthenticated attackers abuse a 'phantom' join key on default configurations to forge access and mint administrator-level credentials. Observed activity includes admin token generation, user, group, and token enumeration, and backdoor user creation in limited cases, raising supply chain poisoning and lateral movement risks for the widely used artifact repository.

Critical GitLab flaw allows attackers to modify or delete public projects (CVE-2026-19478)
GitLab patched a critical unauthenticated code injection flaw CVE-2026-19478 (CVSS 9.4) enabling modification or deletion of public projects; upgrades urged.
GitLab released patches for two vulnerabilities affecting Community Edition (CE) and Enterprise Edition (EE) versions 18.2 before 18.11.11, 19.0 before 19.0.8, 19.1 before 19.1.6, and 19.2 before 19.2.4. CVE-2026-19478 (CVSS 9.4) is an unauthenticated code injection via a GraphQL directive, exploitable remotely without user interaction, allowing attackers to modify or delete public projects and user data. CVE-2026-19650 (CVSS 7.1) is a cross-site request forgery issue in the GraphQL multiplex query handler allowing mutations via GET requests with user interaction. Fixes are available in 18.11.11, 19.0.8, 19.1.6, and 19.2.4; both flaws were reported via GitLab's HackerOne bug bounty program.
