Summary

CVE-2026-6907 is a low-severity Use of Cache Containing Sensitive Information (CWE-524) vulnerability in Djangoproject Django. Its CVSS base score is 2.3 (Low).

Operationally, exploitation aligns with the MITRE ATT&CK technique Unsecured Credentials (T1552); ranked at the 29th 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-3 (Access Enforcement) and SC-4 (Information in Shared System Resources) — see the control section below for these in your framework.

Vulnerability Data

An issue was discovered in 6.0 before 6.0.5 and 5.2 before 5.2.14. `django.middleware.cache.UpdateCacheMiddleware` erroneously caches requests where the `Vary` header contained an asterisk (`'*'`). This can lead to private data being stored and served. Earlier, unsupported Django series (such as…

5.0.x, 4.1.x, and 3.2.x) were not evaluated and may also be affected. Django would like to thank Ahmad Sadeddin for reporting this issue.

Mitigating Controls (NIST 800-53 r5) AI

AC-3 Access Enforcement good match

Enforces access authorizations so that cached sensitive data cannot be read by actors outside the intended sphere.

SC-4 Information in Shared System Resources good match

Directly prevents unauthorized transfer of information through shared resources such as caches.

AC-4 Information Flow Enforcement partial match

Controls information flows to keep sensitive data from leaving its authorized control sphere via caches.

SC-28 Protection of Information at Rest partial match

Requires cryptographic or other protection of sensitive information at rest, which covers cached data.

Mitigating Controls (NIST CSF 2.0) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.

PR.DS-01 mostly match
prevents

Protecting confidentiality of data-at-rest covers caches that persist sensitive information.

PR.AA-05 partial match
prevents

Enforcing least-privilege access permissions directly limits who can read cached sensitive data.

PR.DS-10 partial match
prevents

Protecting data-in-use can mitigate exposure when caches hold transient sensitive values.

PR.IR-01 partial match
prevents

Logical access controls on environments reduce the chance an outsider can reach the cache.

PR.PS-01 partial match
prevents

Hardened configuration baselines can disable or secure caching of sensitive data.

Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

A.8.12 Data leakage prevention mostly match
prevents

Data leakage prevention can block unauthorized access to cached sensitive information.

A.8.3 Information access restriction mostly match
prevents

Information access restriction directly limits who can read cached sensitive data.

A.8.10 Information deletion partial match
mitigates

Information deletion ensures sensitive data is removed from caches when no longer needed.

A.8.24 Use of cryptography partial match
mitigates

Cryptography can protect cached data at rest, but does not address access control scope.

A.8.28 Secure coding partial match
prevents

Secure coding practices prevent caching of sensitive data outside intended boundaries.

A.8.31 Separation of development, test and production environments none match
none

Environment separation reduces risk of cache exposure across development/test/production.
