Critical ArangoDB Flaws Allow Authentication Bypass and Remote Code Execution as Root

Two critical ArangoDB flaws (CVSS 9.8 and 9.9) enable unauthenticated API access and root code execution; fixes shipped in version 3.12.11

Remedio researchers found two ArangoDB flaws: GHSA-rrgq-978q-36mq (CVSS 9.8), an authentication bypass caused by the server inconsistently interpreting URL-encoded '/_api' paths, and GHSA-rvhw-4hpw-9vrx (CVSS 9.9), which lets users with database write access run JavaScript tasks with root privileges via the isSystem flag. Chained, they allow administrative database access without credentials, theft of the root password hash, and root code execution, exposing files such as /etc/shadow, TLS keys and cluster signing material on the official container image. ArangoDB shipped fixes in version 3.12.11 on August 31, 2026, with advisories published September 6; CVE identifiers were still pending. Users on 3.12.10.1 or earlier should upgrade, restrict exposure and rotate potentially exposed credentials.

Rapid7 Analysis: Microsoft SharePoint JWT Token Authentication Bypass (CVE-2026-55040)

Rapid7's analysis of SharePoint auth bypass CVE-2026-55040 includes a PoC for unauthenticated admin-level operations.

Rapid7 and Microsoft disclosed CVE-2026-55040, an authentication bypass in Microsoft SharePoint, on July 14, 2026. The flaw stems from multiple issues in SharePoint's JWT token validation pipeline, allowing a remote unauthenticated attacker to bypass authentication and perform operations as a site user or administrator. Rapid7 has now published a technical analysis and a proof-of-concept script, based on SharePoint Server Subscription Edition.

Flextype v1.0.0-alpha.3 NULL access_token Authentication Bypass

Flextype CMS v1.0.0-alpha.3 API endpoints accept a NULL access_token because isset() validation lets requests bypass authentication.

Flextype CMS v1.0.0-alpha.3 API endpoints can declare access_token as a required parameter, but required-parameter validation only verifies the key exists in the request data. Authentication is then verified inside an isset($data['access_token']) condition, which in PHP treats a NULL value as absent. This allows requests supplying a NULL access_token to bypass authentication on affected endpoints. The flaw was disclosed on the Full Disclosure mailing list on September 3, 2026.

CVE-2026-16232: Checkpoint Quantum Security Management auth bypass ...

Attackers exploit Check Point SmartConsole authentication bypass CVE-2026-16232 to take over Quantum Security Management firewall servers; CISA added it to KEV.

CVE-2026-16232 is an authentication bypass (CWE-287) in the SmartConsole login process of Check Point Quantum Security Management, exploitable via an application token. Disclosed July 22, 2026, it was added to CISA's Known Exploited Vulnerabilities catalog the same day with remediation due July 25. Rapid7, Check Point Research and other vendors confirmed exploitation in the wild, and a public PoC was released. A workaround is available, and federal agencies must comply with BOD 26-04 patching guidance.

Hackers Compromised 14,500+ Dahua Devices Using Credential Attacks, Auth Bypasses, and P2P

Hunt.io disclosed Operation CameraSwarm, compromising 14,500+ Dahua cameras via credential attacks, auth bypass CVEs, and P2P relay techniques across Ukraine and Russia.

Hunt.io reconstructed a campaign codenamed Operation CameraSwarm that compromised over 14,530 Dahua devices between June 17 and July 22, 2026. Attack paths included credential attacks against 12,324 IPs, exploitation of CVE-2021-33044 and CVE-2021-33045 affecting 1,923 cameras, and P2P relay access to 283 devices behind NAT. The operator, assessed as Russian-speaking, left behind 2,616 files including tooling and campaign logs, with confirmed compromises concentrated in Ukraine and Russia. Dahua advises factory resets and firmware updates; both 2021 CVEs remain in CISA's KEV catalog.

CVE-2026-81578 + CVE-2026-82078 | PaperCut NG/MF Authentication Bypass and Unsafe Dynamic Class Loading Vulnerabilities

Two chained PaperCut NG/MF flaws, CVE-2026-81578 and CVE-2026-82078, enable pre-auth RCE, with active exploitation confirmed in customer environments.

PaperCut NG/MF is affected by CVE-2026-81578, an improper access control flaw (CVSS 4.0 8.8) allowing unauthenticated configuration changes, and CVE-2026-82078, an unsafe dynamic class loading flaw (CVSS 4.0 9.4) enabling arbitrary Java bytecode execution. Chained, they yield pre-authentication remote code execution on the PaperCut Application Server. PaperCut confirmed active exploitation and customer incidents, and Huntress observed exploitation starting August 26, 2026. Emergency Patch Release 2 is available for NG/MF v24-v26, with IOCs including suspicious pc-app.exe child processes, truncated server.log files, and AnyDesk installs.
