CVE-2026-15070 + The Salon Booking System – Free Version plugin for WordPress is vulnerable to Cross-Site Request Forgery in al + High + 2026-07-10

One-sentence business risk

Attackers can turn a normal application path into code execution, making this a direct production-host takeover risk.

Research notes

  • Root cause: The Salon Booking System – Free Version plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 10.30.32.
  • Affected versions: wordpresschef Salon Booking System – Free Version: 0 to < 10.30.32.
  • Fixed / safe versions: Vendor-fixed release or mitigation named by the upstream advisory.
  • Public exploit / PoC signal: the consulted NVD/GHSA/vendor sources describe the trigger class; treat it as reproducible until patched.
  • CVSS: 8.8 CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H.

Exact vulnerable code pattern

update_or_read(request.body.target_id)  # no owner/role check

Fixed / mitigated code pattern

target = load_owned_resource(actor, target_id); require_role(actor, target, "admin")

Dependency or runtime update:

composer show invoice-generator || true
composer require invoice-generator --with-all-dependencies
composer audit

Step-by-step integration guide

  1. Inventory invoice-generator across source, lockfiles, SBOMs, container images, CI images, and deployment manifests.
  2. Upgrade to Vendor-fixed release or mitigation named by the upstream advisory or apply the exact vendor patch referenced below.
  3. Replace the vulnerable authz pattern with the fixed pattern and fail closed on malformed input.
  4. Add a regression test that exercises the advisory trigger and proves the request is rejected, bounded, or authorized.
  5. Deploy through canary, monitor security logs and resource metrics, then remove temporary edge blocks only after all runtimes are fixed.

Alternative mitigations

  • Disable the vulnerable feature path while the package/runtime update rolls out.
  • Add WAF or reverse-proxy rules for traversal tokens, prototype-polluting keys, oversized frames, shell metacharacters, or unauthenticated tool calls matching the trigger class.
  • Restrict internal egress, rotate exposed secrets, and revoke affected tokens/keys if the vulnerability can disclose config, logs, JWT secrets, proxy credentials, or PKI material.
  • For admin/API authorization issues, temporarily require elevated roles and explicit ownership checks at the gateway.

Copy-paste skill

You are remediating CVE-2026-15070 (The Salon Booking System – Free Version plugin for WordPress is vulnerable to Cross-Site Request Forgery in al) in this repository.

Find every affected dependency, runtime, image, service configuration, and reachable code path. Upgrade or patch to Vendor-fixed release or mitigation named by the upstream advisory. Replace the vulnerable authz pattern with a fail-closed implementation, add a regression test for the trigger shape, and update deployment/SBOM artifacts. If this repository does not control the affected runtime, create TRIAGE.md naming the owner, affected version, fixed version, and blocking decision.
