{"id":"CVE-2026-1558","state":"PUBLISHED","title":"WP Recipe Maker <= 10.3.2 - Insecure Direct Object Reference to Unauthenticated Arbitrary Post Metadata Modification via 'recipeId' Parameter","description":"The WP Recipe Maker plugin for WordPress is vulnerable to an Insecure Direct Object Reference (IDOR) in versions up to, and including, 10.3.2. This is due to the /wp-json/wp-recipe-maker/v1/integrations/instacart REST API endpoint's permission_callback being set to __return_true and a lack of subsequent authorization or ownership checks on the user-supplied recipeId. This makes it possible for unauthenticated attackers to overwrite arbitrary post metadata (wprm_instacart_combinations) for any post ID on the site via the recipeId parameter.","publishedAt":"2026-02-27T04:33:03.419Z","updatedAt":"2026-04-08T17:06:48.448Z","severity":{"score":5.3,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["brechtvds WP Recipe Maker"],"affected":[{"vendor":"brechtvds","product":"WP Recipe Maker","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"10.3.2","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/90a5589f-f0e9-4511-9c5e-0afcee0824d5?source=cve","https://plugins.trac.wordpress.org/browser/wp-recipe-maker/tags/10.3.2/includes/public/class-wprm-instacart.php#L110","https://plugins.trac.wordpress.org/browser/wp-recipe-maker/tags/10.3.2/includes/public/api/class-wprm-api-integrations.php#L40","https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&new=3464195%40wp-recipe-maker%2Ftrunk&old=3441130%40wp-recipe-maker%2Ftrunk&sfp_email=&sfph_mail="],"weaknesses":["CWE-639"],"ingestedAt":"2026-10-29T20:11:10.572Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/1xxx/CVE-2026-1558.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-1558","state":"PUBLISHED","datePublished":"2026-02-27T04:33:03.419Z","dateUpdated":"2026-04-08T17:06:48.448Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-01-28T18:19:24.671Z"},"containers":{"cna":{"title":"WP Recipe Maker <= 10.3.2 - Insecure Direct Object Reference to Unauthenticated Arbitrary Post Metadata Modification via 'recipeId' Parameter","descriptions":[{"lang":"en","value":"The WP Recipe Maker plugin for WordPress is vulnerable to an Insecure Direct Object Reference (IDOR) in versions up to, and including, 10.3.2.
