An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-1890 exists.\n\nAffected product: Unknown LeadConnector. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-1890/ (Markdown: https://insights.sbomify.com/CVE-2026-1890/index.md)","id":"CVE-2026-1890","markdown":"https://insights.sbomify.com/CVE-2026-1890/index.md","name":"CVE-2026-1890","record":{"aliases":["GHSA-795h-9vq2-6x3x"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"none","summary":"Unauthenticated attackers can overwrite existing data via an unprotected REST route in the LeadConnector WordPress plugin.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[],"cvss":{"score":5.3,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","version":"3.1"},"cwes":[],"description":"The LeadConnector WordPress plugin before 3.0.22 does not have authorization in a REST route, allowing unauthenticated users to call it and overwrite existing data","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":1,"refs":[{"date":null,"kind":"nuclei","ref":"http/cves/2026/CVE-2026-1890.yaml","stars":null,"title":"LeadConnector \u003c 3.0.22 - Unauthenticated Arbitrary Data Write"}],"tier":"weaponised"},"has_fix":null,"headline":"LeadConnector \u003c 3.0.22 - Unauthenticated Rest Call","id":"CVE-2026-1890","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Simple Football Scoreboard \u003c= 1.0 - Authenticated (Contributor+) Stored Cross-Site Scripting via Shortcode Attributes","id":"CVE-2026-1891"},"packages":[],"prev":{"headline":"Outgrow \u003c= 2.1 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'outgrow' Shortcode 'id' Attribute","id":"CVE-2026-1889"},"products":["LeadConnector"],"published":"2026-03-26","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"attribution","licence":"MIT","name":"Nuclei templates"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-03-26","vendors":["Unknown"]},"summary":"Unauthenticated attackers can overwrite existing data via an unprotected REST route in the LeadConnector WordPress plugin.","url":"https://insights.sbomify.com/CVE-2026-1890/"}
