Vulnerability Data

Django-Select2 is a Django integration for Select2. Prior to version 8.4.1, instances of HeavySelect2Mixin subclasses like the ModelSelect2MultipleWidget and ModelSelect2Widget can leak secret access tokens across requests. This can allow users to access restricted query sets and restricted data. This…

Mitigating Controls (NIST 800-53 r5) AI

AC-4 Information Flow Enforcement good match

Explicitly enforces information-flow rules that block private resources from reaching unauthorized external spheres.

AC-3 Access Enforcement good match

Enforces approved authorizations so private resources cannot be transmitted outside their intended sphere.

SI-10 Information Input Validation good match

Input validation directly stops untrusted URLs from being accepted and fetched without destination checks.

SC-7 Boundary Protection partial match

Boundary controls monitor and restrict communications that would otherwise leak private resources.

SC-8 Transmission Confidentiality and Integrity partial match

Requires confidentiality protection on transmitted data, directly stopping exposure of private resources.

PR.AA-05 mostly match
prevents

Enforcing least-privilege access permissions directly prevents private resources from being exposed outside their intended sphere.

PR.IR-01 mostly match
prevents

Logical segmentation and unauthorized-access protections stop resources from leaking into untrusted domains.

PR.PS-06 mostly match
prevents

Secure development practices directly include input validation and destination allow-listing that prevent SSRF.

DE.CM-09 partial match
prevents

Runtime monitoring of web applications and services can detect anomalous outbound requests indicative of SSRF.

ID.RA-01 partial match
prevents

Vulnerability identification processes can discover and record SSRF flaws in web applications.

PR.DS-01 partial match
prevents

Encryption of data-at-rest reduces the value of any leaked resource but does not address the transmission flaw itself.

A.8.3 Information access restriction full match
prevents

Information-access-restriction directly prevents private resources from being exposed beyond intended boundaries.

A.5.15 Access control mostly match
prevents

Access-control mechanisms limit who can receive resources that should remain internal.

A.5.18 Access rights mostly match
prevents

Managing access rights helps ensure resources are not granted to untrusted parties.

A.8.12 Data leakage prevention mostly match
finds

Data-leakage-prevention technologies specifically block unintended transmission of sensitive resources.

A.5.14 Information transfer partial match
mitigates

Information-transfer rules can prevent unintended disclosure of private resources outside the product.

A.5.7 Threat intelligence partial match
prevents

Operational threat data describing SSRF campaigns can be used to tighten outbound-request allow-lists and detection rules before attackers exploit them.

Hardening callouts derived

Configuration rules from DISA STIG baselines that bear on weaknesses of the type cited by this CVE. Each rule is shown with the relationship its mapping actually records, against the CWE it was authored against. Derived via CVE→CWE over `controls_xwalks` (authoritative rows only; rows rated `none` are excluded).
