An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2026-48939 in the wild since at least 10 Jul 2026.\n\nAffected product: icagenda.com iCagenda extension for Joomla. 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-2026-48939/ (Markdown: https://insights.sbomify.com/CVE-2026-48939/index.md)","id":"CVE-2026-48939","markdown":"https://insights.sbomify.com/CVE-2026-48939/index.md","name":"CVE-2026-48939","record":{"aliases":["GHSA-4rh3-rmh3-hv6h"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Joomla iCagenda extension","requires_auth":"none","summary":"Attackers can upload arbitrary PHP files via the attachment feature to execute remote code on Joomla sites using the iCagenda extension.","user_interaction":"not_required","vuln_class":"file_upload"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Joomla","cpe":[{"product":"icagenda","vendor":"joomlic"}],"cvss":{"score":10,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H/E:A/AU:Y/U:Red","version":"4.0"},"cwes":[{"id":"CWE-434","name":"Unrestricted Upload of File with Dangerous Type"}],"description":"A vulnerability in the iCagenda extension for Joomla allows the upload of arbitrary files in the file attachment feature, ultimately resulting in PHP code upload and execution.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2026-06-29","github_poc":3,"max_poc_stars":2,"metasploit":0,"nuclei":1,"refs":[{"date":"2026-07-05T20:56:48Z","kind":"github_poc","ref":"https://github.com/shinthink/CVE-2026-48939","stars":2,"title":"Pre-auth arbitrary file upload RCE exploit for iCagenda Joomla extension \u003c 4.0.8 (CVSS 10.0)"},{"date":"2026-06-29T11:09:38Z","kind":"github_poc","ref":"https://github.com/Polosss/By-Poloss..-..CVE-2026-48939","stars":1,"title":"iCagenda Unauthenticated File Upload to RCE"},{"date":"2026-07-18T22:02:28Z","kind":"github_poc","ref":"https://github.com/ChiefYoru/CVE-2026-48939_PoC","stars":0,"title":"iCagenda extension for Joomla allows the upload of arbitrary files in the file attachment feature, ultimately resulting in PHP code upload and execution."},{"date":null,"kind":"nuclei","ref":"http/cves/2026/CVE-2026-48939.yaml","stars":null,"title":"Joomla iCagenda \u003c 3.9.10 - Unauthenticated Arbitrary File Upload RCE"}],"tier":"exploited"},"has_fix":null,"headline":"iCagenda Unrestricted Upload of File with Dangerous Type","id":"CVE-2026-48939","indexable":true,"kev":{"dateAdded":"2026-07-10","dueDate":"2026-07-13","knownRansomwareCampaignUse":"Unknown","product":"iCagenda","requiredAction":"Apply mitigations in accordance with vendor instructions, ensuring compliance with CISA’s BOD 26-04 Prioritizing Security Updates Based on Risk (see URL in Notes) guidance and CISA’s “Forensics Triage Requirements” (see URL in Notes).
