{"cve":"CVE-2026-15348","nvd":{"published":"2026-07-23T10:16:50.303","modified":"2026-07-23T15:14:51.013","status":"Deferred","description":"The Premium Packages – Sell Digital Products Securely plugin for WordPress is vulnerable to Authentication Bypass in all versions up to, and including, 7.0.4 via the `wpdmppdl` parameter. This is due to the `download()` function — hooked to the unauthenticated WordPress `wp` action — decoding the attacker-controlled `wpdmppdl` parameter using only `base64_decode()` and `json_decode()` with no HMAC, cryptographic signature, or nonce verification, and then issuing WordPress authentication cookies after a domain check that is trivially bypassed because both sides of the comparison are attacker-supplied values. This makes it possible for unauthenticated attackers to authenticate as any non-administrator WordPress user, including subscribers, customers, contributors, authors, editors, and shop managers, who owns an order, gaining full session-level access to that account.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L","score":6.3},"cwes":["CWE-287"],"references":["https://plugins.trac.wordpress.org/browser/wpdm-premium-packages/tags/7.0.0/includes/libs/functions.php#L1811","https://plugins.trac.wordpress.org/browser/wpdm-premium-packages/tags/7.0.0/wpdm-premium-packages.php#L119","https://plugins.trac.wordpress.org/browser/wpdm-premium-packages/tags/7.0.0/wpdm-premium-packages.php#L585","https://plugins.trac.wordpress.org/browser/wpdm-premium-packages/tags/7.0.0/wpdm-premium-packages.php#L632","https://plugins.trac.wordpress.org/browser/wpdm-premium-packages/tags/7.0.0/wpdm-premium-packages.php#L637"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:45:53.305392138+00:00"},"epss":{"cve":"CVE-2026-15348","score":0.00581,"percentile":0.47792,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
