Three technical stories from today’s recap:

Ubuntu container escape: DepthFirst released an exploit for CVE-2026-80521 that reaches host root from a container on Ubuntu 26.04. The AF\UNIX flaw was fixed upstream, but affected distribution kernels still need the patch.

F5 BIG-IP APM RCE: CVE-2026-94127 is being exploited against vulnerable OAuth authorization-server configurations. Management-interface access is not required. Hotfixes are available.

Process Parameter Poisoning: Flashpoint tested Windows code injection through process initialization structures, avoiding common memory-writing APIs. The technique produced no alerts from the EDR controls tested in its lab.

More technical details and source links in today’s recap on CyberRecaps, and have an amazing day :)

Adobe Campaign Classic (ACC) is affected by an Improper Control of Generation of Code ('Code Injection') vulnerability that could result in arbitrary code execution in the context of the current user. A low-privileged attacker could exploit this vulnerability to execute arbitrary code. Exploitation of this issue does not require user interaction. Scope is changed.

There is a stored cross site scripting issue in Esri ArcGIS Server 11.4 and earlier on Windows and Linux that in some configurations allows a remote unauthenticated attacker to store files that contain malicious code that may execute in the context of a victim’s browser.

ArcGIS Server versions 11.5 and earlier on Windows and Linux do not sufficiently validate uploaded files, enabling a remote unauthenticated attacker to upload arbitrary files to the server’s designated upload directories.

However, the server’s architecture enforces controls that restrict uploaded files to non‑executable storage locations and prevent modification or replacement of existing application components or system configurations. Uploaded files cannot be executed, leveraged to escalate privileges, or used to access sensitive data.

Because the issue does not enable execution, service disruption, unauthorized access, or integrity compromise, its impact on confidentiality, integrity, and availability is low. Note that race conditions, secret values, or man‑in‑the‑middle conditions are required for exploitation.
