Affected is the function nlp.extend of the file src/API/extend.js of the component Public Root API. The manipulation of the argument plugin leads to improperly controlled modification of object prototype attributes. Remote exploitation of the attack is possible. The exploit is publicly available and might be used. The identifier of the patch is b4644ab7179700df0607521f61c1ee9b5f78d89d. Applying a patch is the recommended action to fix this issue. The vendor was contacted early, responded in a very professional manner and quickly released a fixed version of the affected product.","publishedAt":"2026-07-14T15:45:08.286Z","updatedAt":"2026-07-14T17:52:49.267Z","severity":{"score":5.3,"label":"Medium","version":"4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:P","source":"VulDB"},"assigner":"VulDB","products":["spencermountain compromise"],"affected":[{"vendor":"spencermountain","product":"compromise","versions":[{"version":"14.15.0","status":"affected"},{"version":"14.15.1","status":"affected"}],"cpes":["cpe:2.3:a:spencermountain:compromise:*:*:*:*:*:*:*:*"],"modules":["Public Root API"]}],"references":["https://vuldb.com/vuln/378246","https://vuldb.com/vuln/378246/cti","https://vuldb.com/cve/CVE-2026-15699","https://vuldb.com/submit/856016","https://github.com/spencermountain/compromise/issues/1208","https://github.com/spencermountain/compromise/commit/b4644ab7179700df0607521f61c1ee9b5f78d89d","https://github.com/spencermountain/compromise/"],"weaknesses":["CWE-1321","CWE-94"],"ingestedAt":"2026-10-29T20:11:00.674Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/15xxx/CVE-2026-15699.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-15699","state":"PUBLISHED","datePublished":"2026-07-14T15:45:08.286Z","dateUpdated":"2026-07-14T17:52:49.267Z","assignerShortName":"VulDB","assignerOrgId":"1af790b2-7ee1-4545-860a-a788eba489b5","dateReserved":"2026-07-14T05:12:43.606Z"},"containers":{"cna":{"title":"spencermountain compromise Public Root API extend.js nlp.extend prototype pollution","descriptions":[{"lang":"en","value":"A vulnerability was identified in spencermountain compromise up to 14.15.1.
