CediPay Affected by Improper Input Validation in Payment Processing

CVE-2026-26063GHSA-wvr6-395c-5pxr

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (cedipay-core 1.2.3), redeploy, then verify what is actually installed.

This page has no inventory attached, so it cannot say whether you are affected. A vendor fix is not proof that your deployment is fixed.

Source description

As published by the source; long descriptions are shortened.

A vulnerability in CediPay allows attackers to bypass input validation in the transaction API. Affected users: All deployments running versions prior to the patched release. Risk: Exploitation could result in unauthorized transactions, exposure of sensitive financial data, and compromise of payment integrity. Severity: High — potential financial loss and reputational damage. Patches The issue has been fixed in version 1.2.3. Users should upgrade to 1.2.3 or later immediately. All versions earlier than 1.2.3 remain vulnerable. Workarounds If upgrading is not immediately possible: Restrict API access to trusted networks or IP ranges. Enforce strict input validation at the application layer. Monitor transaction logs for anomalies or suspicious activity. These mitigations reduce exposure but do not fully eliminate the vulnerability.

# Patch Next advisory brief: CVE-2026-26063

Advisory: CediPay Affected by Improper Input Validation in Payment Processing
IDs: CVE-2026-26063, GHSA-wvr6-395c-5pxr
Record: https://patchnext.com/advisories/cve-2026-26063 (revision 3, source checked 26 Oct 2026, 12:42 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 8.8)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: cedipay-core 1.2.3. A vendor fix does not mean a deployment is fixed.

## Affected components
- npm cedipay-core: affected < 1.2.3; fixed in 1.2.3

## Suggested inspection (read-only)
- `npm ls cedipay-core --all`: lists every installed copy and version, including transitive ones. Run in the project root after `npm ci`.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on cedipay-core.
- 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://osv.dev/vulnerability/GHSA-wvr6-395c-5pxr (OSV record GHSA-wvr6-395c-5pxr lists affected ranges: npm cedipay-core >=0 <1.2.3 (fixed))
- Verified: https://github.com/advisories/GHSA-wvr6-395c-5pxr (GitHub-reviewed advisory GHSA-wvr6-395c-5pxr lists affected ranges: npm cedipay-core >=0 <1.2.3)
