Summary

CVE-2026-87744 is a critical-severity Forced Browsing (CWE-425) vulnerability. Its CVSS base score is 9.1 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Proc Filesystem (T1003.007); ranked at the 20th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to AC-24 (Access Control Decisions) and AC-3 (Access Enforcement) — see the control section below for these in your framework.

Vulnerability Data

A flaw was found in Quarkus REST Data Panache. This vulnerability allows unauthenticated attackers to bypass security controls on generated endpoints. When a developer customizes a specific operation using @MethodProperties without explicitly re-declaring security roles, the code generator silently drops…

class-level security requirements. This results in the affected endpoint defaulting to permissive, unauthenticated access, potentially leading to unauthorized information disclosure or data modification.

MITRE ATT&CK Enterprise Techniques

T1003.007 Proc Filesystem Credential Access
Adversaries may gather credentials from the proc filesystem or `/proc`.
T1005 Data from Local System Collection
Adversaries may search local system sources, such as file systems, configuration files, local databases, virtual machine files, or process memory, to find files of interest and sensitive data prior to Exfiltration.
T1010 Application Window Discovery Discovery
Adversaries may attempt to get a listing of open application windows.
T1011.001 Exfiltration Over Bluetooth Exfiltration
Adversaries may attempt to exfiltrate data over Bluetooth rather than the command and control channel.
T1012 Query Registry Discovery
Adversaries may interact with the Windows Registry to gather information about the system, configuration, and installed software.
T1016 System Network Configuration Discovery Discovery
Adversaries may look for details about the network configuration and settings, such as IP and/or MAC addresses, of systems they access or through information discovery of remote systems.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

AC-24 requires that access-control decisions be applied to every request, addressing the missing enforcement on restricted URLs.

AC-3 directly requires enforcement of authorizations for access to resources such as URLs, scripts, and files, structurally preventing forced browsing.

Directly requires policy-driven definition, enforcement, and review of authorizations on resources such as URLs.

blocks

A.5.15 directly requires defining/implementing access control rules, authorization, need-to-know, and restrictions that enforce appropriate access on all URLs/resources, which stops forced browsing exploitation even if the flaw remains; remainder is bounded to non-authorization cases like path traversal or CSRF (per AC-3 anchor).
