CVE-2025-8049 Overview
CVE-2025-8049 is an insufficient granularity of access control vulnerability [CWE-1220] affecting OpenText Flipper version 3.1.2. The flaw allows a low-privilege authenticated user to elevate privileges within the application by exploiting incorrectly configured access control security levels. The vendor, OpenText, has acknowledged the issue in a security advisory.
The vulnerability requires user interaction and high attack complexity, which limits practical exploitation. No public proof-of-concept code or in-the-wild exploitation has been reported.
Critical Impact
Authenticated low-privilege users can escalate privileges inside OpenText Flipper, gaining access to functionality intended for higher-privilege accounts.

Technical Details for CVE-2025-8049
Vulnerability Analysis
The vulnerability resides in the access control enforcement layer of OpenText Flipper 3.1.2. The application defines security levels for separating user privileges, but the enforcement granularity is insufficient. As a result, the boundary between low-privilege and higher-privilege actions can be crossed by an authenticated user issuing crafted requests.
Because the flaw is a broken access control issue rather than a memory or injection bug, exploitation does not require malicious payloads. An attacker leverages legitimate application functionality with manipulated parameters or endpoint access that should have been restricted.
The weakness maps to [CWE-1220], Insufficient Granularity of Access Control. This class of issue typically appears when an application checks coarse role membership instead of validating per-action or per-resource authorization.
Root Cause
The root cause is incorrectly configured access control security levels within Flipper. Role definitions or permission checks do not adequately separate sensitive operations from those available to standard users. The application trusts session-level role assignment without revalidating authorization at the resource or action boundary.
Attack Vector
The attack vector is network-based and requires the attacker to already hold a valid low-privilege account. User interaction is required, and attack complexity is high, meaning the attacker must satisfy specific conditions to trigger the escalation path. Successful exploitation yields limited confidentiality, integrity, and availability impact within the application scope.
No verified exploitation code is publicly available. See the OpenText Security Advisory for technical details.
Detection Methods for CVE-2025-8049
Indicators of Compromise
- Application audit log entries showing low-privilege accounts accessing administrative endpoints or features in Flipper.
- Unexpected changes to user roles, permissions, or configuration objects performed by non-administrative accounts.
- HTTP requests to privileged Flipper API paths originating from sessions tied to standard users.
Detection Strategies
- Review Flipper application logs for actions performed by accounts whose assigned role should not permit those operations.
- Correlate authentication events with subsequent privileged action events to identify anomalous role-to-action mismatches.
- Compare current effective permissions in Flipper against the documented role matrix to surface drift or misconfiguration.
Monitoring Recommendations
- Enable verbose audit logging in Flipper and forward events to a centralized log platform for retention and analysis.
- Alert on first-time access patterns where a user account performs an action outside its historical baseline.
- Monitor administrative configuration changes and require out-of-band verification for sensitive operations.
How to Mitigate CVE-2025-8049
Immediate Actions Required
- Review the OpenText Security Advisory KB0850530 and apply vendor-provided guidance for Flipper 3.1.2.
- Audit all Flipper user accounts and remove unnecessary privileges, enforcing least privilege across roles.
- Restrict network access to the Flipper application so that only authorized users can reach the interface.
Patch Information
OpenText has published advisory KB0850530 covering this issue. Administrators should consult the OpenText Security Advisory for the recommended fixed version and upgrade procedure for Flipper.
Workarounds
- Tighten access control configuration to ensure security levels are explicitly defined for each sensitive action.
- Disable or restrict low-privilege account creation until the patched version is deployed.
- Place the Flipper application behind authenticated reverse-proxy controls that enforce additional authorization checks.
# Configuration example
# Review Flipper role assignments and revoke unnecessary privileges
# Refer to OpenText KB0850530 for vendor-specific configuration steps
