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-2026-18603 exists.\n\nAffected product: Unknown PiWeb Cancel order / Refund request for WooCommerce. 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-2026-18603/ (Markdown: https://insights.sbomify.com/CVE-2026-18603/index.md)","id":"CVE-2026-18603","markdown":"https://insights.sbomify.com/CVE-2026-18603/index.md","name":"CVE-2026-18603","record":{"aliases":["GHSA-39g4-r8qh-2jjf"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"none","summary":"Unauthenticated attackers can view other customers' order contents and modify logged-in users' carts due to missing authorization checks in the plugin.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[],"cvss":{"score":6.5,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"}],"description":"The PiWeb Cancel order / Refund request for WooCommerce WordPress plugin before 1.3.4.34 does not have authorization or ownership checks when adding the contents of a previous order to the cart, allowing unauthenticated users to disclose the contents of other customers' orders, as well as to clear and repopulate a logged in user's cart via a crafted link.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":null,"headline":"Cancel Order \u0026 Request Woocommerce \u003c 1.3.4.34 - Unauthenticated Order Content Disclosure via Reorder AJAX Actions","id":"CVE-2026-18603","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":"textPlus Text Message and Call App com.gogii.textplus DialerActivity improper export of android application components","id":"CVE-2026-18604"},"packages":[],"prev":{"headline":"GL.iNet GL-MT3000 ovpn-client.so Native Plugin glc ovpn-client.get_recommend_config command injection","id":"CVE-2026-18602"},"products":["PiWeb Cancel order / Refund request for WooCommerce"],"published":"2026-08-09","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":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-08-10","vendors":["Unknown"]},"summary":"Unauthenticated attackers can view other customers' order contents and modify logged-in users' carts due to missing authorization checks in the plugin.","url":"https://insights.sbomify.com/CVE-2026-18603/"}
