Active Exploitation Attempts Target WSO2 API Manager JWT Bypass With Forged Admin Tokens

WatchTowr confirmed active in-the-wild exploitation of CVE-2026-5430 in WSO2 API Manager (CVSS 9.8), capturing forged admin-privilege JWT tokens on its honeypot network on September 13, 2026; vendor fixes ship as pull requests and update levels spanning API Manager 4.1.0 through 4.6.0, API Control Plane, Traffic Manager, and Universal Gateway. Acronis separately reported limited, targeted exploitation of CVE-2026-87886 in its cPanel/WHM backup plugin based on a single customer report, while CISA added CVE-2026-76461, a Cisco Secure Email Gateway SQL injection, to its Known Exploited Vulnerabilities catalog.

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

CISA added CVE-2026-85706 to its KEV catalog on September 11 after watchTowr observed in-the-wild probes against GitLab's unauthenticated repository-commits API path traversal (CVSS 10.0); self-managed instances should patch to 19.1.8, 19.2.6, or 19.3.2 and review HTTP POST requests to /api/v4/projects/{id}/repository/commits/ URIs containing file.Path parameters. Separately, Wiz confirmed that multiple actors chained CVE-2026-42018 and CVE-2026-42016 against self-hosted JFrog Artifactory between August 15 and September 8 to mint admin tokens, install malicious Groovy plugins, and deploy a Rust-based backdoor, with 49–62% of reachable instances vulnerable to at least one of the three flaws.

Week in review: Claude accounts compromised through infostealer, Patch Tuesday forecast

Attackers have been exploiting an unpatched, unauthenticated code-execution vulnerability in all current versions of Magento Open Source and Adobe Commerce since September 4, planting a persistent Rust backdoor under a fake kernel-thread name; with no vendor fix before Adobe's September 8 release, Sansec and Disrex recommend disabling GraphQL, adding proc_open to disable_functions, mounting /tmp and /dev/shm with noexec, and—on already-compromised hosts—removing the cron entry before killing the process, then rotating the crypt key, all admin passwords, and every payment-provider API key in app/etc/env.php. In the same period, SonicWall confirmed active exploitation of two zero-days in SMA 1000 appliances, a threat actor is actively targeting internet-exposed Sangoma Switchvox instances through a recently patched SQL injection, and JetBrains disclosed that attackers breached its Cadence cloud service via an unpatched TeamCity deserialization flaw, extracting AWS IAM credentials from a 2024 backup and prompting all users to revoke every credential and treat all prior executions as untrusted.

VulnCheck logged 360 detections of CVE-2026-0768 and CVE-2026-66066 exploitation against Langflow and Rails hosts, with attackers harvesting API keys and cloud credentials from environment variables, and noted that a patched 8.1.3.1 server still executes the RCE gadget through variation-key Marshal deserialization.
