Critical GitLab GraphQL Flaw Could Let Unauthenticated Attackers Delete Public Projects

GitLab urgently patched CVE-2026-19478 (CVSS 9.4), a critical unauthenticated GraphQL flaw allowing modification or deletion of public projects on self-managed instances.

GitLab released an out-of-band critical patch on August 17, 2026 fixing CVE-2026-19478 (CVSS 9.4), a flaw that under certain conditions lets unauthenticated attackers remotely modify or delete public projects and user data via a GraphQL directive in Community and Enterprise Editions. Fixes are available in GitLab 19.2.4, 19.1.6, 19.0.8, and 18.11.11; GitLab.com and GitLab Dedicated are already patched, so only self-managed installations need to act. The release also fixes CVE-2026-19650 (CVSS 7.1), a cross-site request forgery flaw in GraphQL multiplex query handling requiring user interaction. No exploitation or public exploit code has been observed as of August 18, 2026.

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.

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.

GitLab CVSS 10 File-Read Flaw Draws In-the-Wild Probes After Disclosure

GitLab patched CVE-2026-85706, a CVSS 10.0 unauthenticated path traversal enabling arbitrary file reads, already probed in the wild.

GitLab released patches for a maximum-severity path traversal flaw (CVE-2026-85706, CVSS 10.0) in the repository commits API, caused by improper path confinement and missing authentication enforcement, allowing unauthenticated arbitrary file reads. watchTowr observed active in-the-wild probes starting 06:00 UTC on September 11, 2026; exploitation requires at least one public project and enables theft of credentials, secrets, and configuration data. GitLab also patched CVE-2026-87719 (CVSS 9.9), an insecure deserialization bug in Enterprise Edition allowing authenticated Duo Chat users to access Advanced Search configurations and sensitive credentials via crafted GraphQL subscription arguments. Affected versions include 18.7 before 19.1.8, 19.2 before 19.2.6, and 19.3 before 19.3.2, and the flaw follows the recently exploited GraphQL code injection bug CVE-2026-19478.

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.

Emerging Threat: (CVE-2026-60004) Gitea Remote Code Execution via ...

CVE-2026-60004 (CVSS 9.8) lets attackers with repository write access achieve RCE on self-hosted Gitea servers via malicious git hooks; fixed in 1.27.1.

CVE-2026-60004 is a CWE-94 code injection flaw in Gitea's POST /api/v1/repos/{owner}/{repo}/diffpatch endpoint, disclosed July 28, 2026 with a CVSS v3.1 score of 9.8 and credited to researcher Shai Rod (NightRang3r). An add/add collision with the three-way merge fallback (--3, Git 2.32+) writes attacker-controlled content into the temporary bare clone's hooks directory, where it executes as a live Git hook running commands as the Gitea OS user. Exploitation requires repository write access, but Gitea's default open registration allows anonymous users to obtain it, exposing app.ini secrets, database credentials, OAuth tokens, and mounted repositories; a public PoC requires no outbound callback. All releases from 1.17 through 1.27.0 are affected; the fix shipped in Gitea 1.27.1 on July 27, 2026, and Gitea Cloud instances were upgraded automatically.

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.

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.
