An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-4880 in the wild and no public exploit code.\n\nAffected product: ukrsolution Barcode Scanner (+Mobile App) – Inventory manager, Order fulfillment system, POS (Point of Sale). 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-2026-4880/ (Markdown: https://insights.sbomify.com/CVE-2026-4880/index.md)","id":"CVE-2026-4880","markdown":"https://insights.sbomify.com/CVE-2026-4880/index.md","name":"CVE-2026-4880","record":{"aliases":["GHSA-p8x8-wgf2-jrjm"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["privilege_escalation","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"none","summary":"Unauthenticated attackers can escalate privileges to administrator by spoofing user IDs to leak tokens and modifying capabilities in the Barcode Scanner WordPress plugin.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Wordfence","cpe":[],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-269","name":"Improper Privilege Management"}],"description":"The Barcode Scanner (+Mobile App) – Inventory manager, Order fulfillment system, POS (Point of Sale) plugin for WordPress is vulnerable to privilege escalation via insecure token-based authentication in all versions up to, and including, 1.11.0. This is due to the plugin trusting a user-supplied Base64-encoded user ID in the token parameter to identify users, leaking valid authentication tokens through the 'barcodeScannerConfigs' action, and lacking meta-key restrictions on the 'setUserMeta' action. This makes it possible for unauthenticated attackers to escalate their privileges to that of an administrator by first spoofing the admin user ID to leak their authentication token, then using that token to update any user's 'wp_capabilities' meta to gain full administrative access.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Barcode Scanner (+Mobile App) \u003c= 1.11.0 - Unauthenticated Privilege Escalation via Insecure Token Authentication","id":"CVE-2026-4880","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"privilege_escalation","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"Missing authorization in Octopus Server","id":"CVE-2026-4881"},"packages":[],"prev":{"headline":"Missing Authorization in GitLab","id":"CVE-2026-4879"},"products":["Barcode Scanner (+Mobile App) – Inventory manager, Order fulfillment system, POS (Point of Sale)"],"published":"2026-04-15","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-04-16","vendors":["ukrsolution"]},"summary":"Unauthenticated attackers can escalate privileges to administrator by spoofing user IDs to leak tokens and modifying capabilities in the Barcode Scanner WordPress plugin.","url":"https://insights.sbomify.com/CVE-2026-4880/"}
