CVE-2026-77776 – Cross-User Memory Disclosure/Manipulation via Header Spoofing – Headroom (headroom-

Be the first to know when new zero-days emerge:

Summary

CVE-2026-77776 is a critical authorization bypass vulnerability (CWE-639: Authorization Bypass Through User-Controlled Key) affecting Headroom, an open-source LLM context/memory proxy distributed as the headroom-ai package. The proxy’s OpenAI-compatible request handler trusts the client-supplied x-headroom-user-id HTTP header as a caller’s identity without binding it to any authenticated session, allowing a remote, unauthenticated attacker to read or write another user’s stored LLM memory simply by naming their user identifier. The issue carries a CVSS v3.1 base score of 9.1 (Critical).

Technical details

  • Root cause: headroom/proxy/handlers/openai.py (and related memory-handling code in headroom/proxy/memory_handler.py and headroom/memory/easy.py) reads the x-headroom-user-id header directly and uses it as the identity key for the memory store, without verifying that the header value corresponds to the actual authenticated caller.
  • Trigger conditions: Any client able to reach the Headroom proxy’s OpenAI-compatible API endpoint can set an arbitrary x-headroom-user-id value in the request header to impersonate another user’s memory namespace.
  • Compounding factor: The project’s reference Docker Compose configuration exposes the proxy to the network without requiring a proxy authentication token, making the flaw remotely exploitable by default in that deployment pattern.
  • Attack vector: Network (AV:N), low attack complexity, no privileges or user interaction required.
  • Impact: Confidentiality impact is high — an attacker can read another user’s persisted LLM conversation/memory data by supplying their user ID. The CVSS vector for this CVE (C:H/I:H/A:N) also reflects an integrity impact, consistent with the ability to write/poison another user’s stored memory, while availability is not affected.

Affected software

  • Headroom (headroom-ai PyPI package) versions 0 through 0.36.0
  • Fixed in version 0.36.1 and later

Severity

  • CVSS v3.1 Base Score: 9.1 (Critical)
  • Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N

Mitigation and recommended actions

  • Immediate: Upgrade Headroom to version 0.36.1 or later, which introduces a centralized resolve_memory_identity() function that only honors the x-headroom-user-id header for loopback or explicitly allowlisted callers; for all other (remote) requests, identity is bound to the proxy-token fingerprint instead of the client-supplied header.
  • If unable to patch immediately:
    • Require and enforce a proxy authentication token (HEADROOM_PROXY_TOKEN) for all deployments — do not run the reference Docker Compose configuration without setting this value.
    • Restrict network exposure of the Headroom proxy so it is reachable only from trusted/loopback hosts, and avoid publishing its ports directly to untrusted networks.
    • Audit any existing deployments for evidence of cross-user memory access via manipulated x-headroom-user-id headers before patching.

Dozens of threat intel feeds using agentic technology are continuously analyzed to detect the appearance of proof-of-concept code, exploit kits, and indicators of active targeting. IONIX goes further by applying AI to proactively evaluate whether emerging vulnerabilities are likely to be exploited, even before PoCs go public.

3

Identify Potential External Exposures

Not all CVEs matter. IONIX filters vulnerabilities by asking attacker-centric questions: Can it be reached from the internet? Does it require authentication? Is it being exploited in the wild? This dramatically reduces noise and focuses teams on threats that can actually be weaponized.

4

Create Safe, Scalable Exploit Validations

IONIX transforms real-world PoCs into safe, non-intrusive test payloads that can be run in production environments without disruption. These simulations are precisely targeted to the systems that are vulnerable, ensuring rapid validation without unnecessary load.

5

Execute Exploit Validations

By combining context about software stack, versioning, exposure status, and reachability, IONIX ensures that only the right payloads are executed against the right assets, maximizing efficiency and minimizing risk.

6

Drive Fast and Actionable Remediation

Results are routed through integrations with ticketing, SOAR, and SIEM tools. Issues are written in plain language, bundled into remediation clusters, and prioritized based on asset criticality, exploitability, and blast radius. This shortens mean time to remediation (MTTR) and empowers teams to act with confidence.
