This is due to the use of a weak authentication token for the /wp-json/salesmanago/v1/callbackApiV3 API endpoint which is simply a SHA1 hash of the site URL and client ID found in the page source of the website. This makes it possible for unauthenticated attackers to inject arbitrary content into the log files, and when combined with another vulnerability this could have significant consequences.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","score":5.3},"cwes":["CWE-305","CWE-287"],"references":["https://plugins.trac.wordpress.org/browser/salesmanago/trunk/src/Admin/Controller/CallbackController.php","https://plugins.trac.wordpress.org/browser/salesmanago/trunk/src/Includes/Helper.php#L376","https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&old=2981700%40salesmanago&new=2981700%40salesmanago&sfp_email=&sfph_mail=","https://www.wordfence.com/threat-intel/vulnerabilities/id/de7db1d6-b352-44c7-a6cc-b21cb65a0482?source=cve","https://plugins.trac.wordpress.org/browser/salesmanago/trunk/src/Admin/Controller/CallbackController.php"],"products":["salesmanago:salesmanago"],"source":"nvd","synced_at":"2026-10-19T21:40:11.519948003+00:00"},"epss":{"cve":"CVE-2023-4939","score":0.00638,"percentile":0.50579,"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).
