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-2026-13143 exists.\n\nAffected product: Unknown WP Travel. 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-2026-13143/ (Markdown: https://insights.sbomify.com/CVE-2026-13143/index.md)","id":"CVE-2026-13143","markdown":"https://insights.sbomify.com/CVE-2026-13143/index.md","name":"CVE-2026-13143","record":{"aliases":["GHSA-vx7q-rhxw-6x3x"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["data_modify","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"none","summary":"Unauthenticated attackers can forge PayPal IPN notifications to mark bookings as paid, bypassing payment verification in WP Travel.","user_interaction":"not_required","vuln_class":"business_logic"},"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":[{"id":"CWE-290","name":"Authentication Bypass by Spoofing"}],"description":"The WP Travel  WordPress plugin before 11.8.1 does not verify PayPal Instant Payment Notifications through the PayPal post-back handshake before marking a booking paid, allowing unauthenticated attackers to forge a notification that flips an arbitrary pending booking to a paid and booked state at an attacker-chosen amount.","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":"WP Travel \u003c 11.8.1 - Unauthenticated Payment Bypass via Forged PayPal IPN","id":"CVE-2026-13143","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"business_logic","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"WP Travel \u003c 12.0.2 - Unauthenticated Arbitrary Booking Payment Reset","id":"CVE-2026-13144"},"packages":[],"prev":{"headline":"Passwordless Login by VentraConnect \u003c 1.4.1 - Unauthenticated Account Takeover via Email OTP Brute Force","id":"CVE-2026-13142"},"products":["WP Travel"],"published":"2026-07-30","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":"2026-07-30","vendors":["Unknown"]},"summary":"Unauthenticated attackers can forge PayPal IPN notifications to mark bookings as paid, bypassing payment verification in WP Travel.","url":"https://insights.sbomify.com/CVE-2026-13143/"}
