• CVE-2026-41696: 0.26% estimated exploitation activity in the next 30 days; percentile 18.08 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

Spring Data MongoDB repository query methods annotated with @Query that use regex parameter binding perform insufficient validation of the bound parameter. An attacker can supply a crafted string to break out of the intended regular expression quoting. Affected versions: Spring Data MongoDB 5.0.0 through 5.0.5; 4.5.0 through 4.5.11; 4.4.0 through 4.4.14; 4.3.0 through 4.3.16; 4.2.0 through 4.2.15; 4.1.0 through 4.1.14; 4.0.0 through 4.0.15; 3.4.0 through 3.4.19.

# Patch Next advisory brief: CVE-2026-41696

Advisory: Spring Data MongoDB Has Regex Parameter Binding Injection in @Query Repository Methods
IDs: CVE-2026-41696, GHSA-hc43-m36c-8v33
Record: https://patchnext.com/advisories/cve-2026-41696 (revision 1, source checked 26 Oct 2026, 16:54 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 5.9)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Partial vendor fix; fixed versions by package: org.springframework.data:spring-data-mongodb 5.0.6, 4.5.12. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven org.springframework.data:spring-data-mongodb: affected >= 5.0.0, <= 5.0.5; >= 4.5.0, <= 4.5.11; >= 4.4.0, <= 4.4.14; >= 4.0.0, <= 4.3.16; <= 3.4.19; fixed in 4.5.12, 5.0.6

## Suggested inspection (read-only)
- Maven org.springframework.data:spring-data-mongodb: check the installed version with your package manager.

## Supported action
No complete vendor fix is recorded. Follow the primary source's mitigation guidance and check this record again before closing anything.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on org.springframework.data:spring-data-mongodb.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://github.com/advisories/GHSA-hc43-m36c-8v33 (GitHub-reviewed advisory GHSA-hc43-m36c-8v33 lists affected ranges: Maven org.springframework.data:spring-data-mongodb >=5.0.0 =4.5.0 =4.4.0 =4.0.0 =0 <=3.4.19)
