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-2026-13423 in the wild and no public exploit code.\n\nAffected product: Unknown Streamit. 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-2026-13423/ (Markdown: https://insights.sbomify.com/CVE-2026-13423/index.md)","id":"CVE-2026-13423","markdown":"https://insights.sbomify.com/CVE-2026-13423/index.md","name":"CVE-2026-13423","record":{"aliases":["GHSA-fvvp-v9c4-343h"],"analysis":{"component_type":"cms_plugin","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress theme","requires_auth":"none","summary":"Unauthenticated attackers can execute arbitrary PHP functions via an insecure AJAX route, leading to remote code execution and privilege escalation.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[],"cvss":{"score":9.8,"severity":"critical","source":"cisa-adp","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-94","name":"Improper Control of Generation of Code"}],"description":"The Streamit WordPress theme through 4.5.0 does not perform any authorization or nonce verification on one of its unauthenticated AJAX routes, which invokes an attacker-supplied PHP function with an attacker-supplied argument array, allowing unauthenticated attackers to call arbitrary functions (for example to create an administrator account), leading to privilege escalation and remote code execution.","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":"Streamit \u003c= 4.5.0 - Unauthenticated Remote Code Execution via Arbitrary Function Call","id":"CVE-2026-13423","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"code_injection","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Cross-site scripting in Online Scheduling and Appointment Booking System – Bookly","id":"CVE-2026-13424"},"packages":[],"prev":{"headline":"HD Quiz 2.2.0 - 2.2.1 - Cross-Site Request Forgery via Multiple AJAX Handlers","id":"CVE-2026-13422"},"products":["Streamit"],"published":"2026-07-29","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":"2026-07-29","vendors":["Unknown"]},"summary":"Unauthenticated attackers can execute arbitrary PHP functions via an insecure AJAX route, leading to remote code execution and privilege escalation.","url":"https://insights.sbomify.com/CVE-2026-13423/"}
