Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-48799 in the wild and no public exploit code.\n\nAffected product: gitroomhq postiz-app. 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-2026-48799/ (Markdown: https://insights.sbomify.com/CVE-2026-48799/index.md)","id":"CVE-2026-48799","markdown":"https://insights.sbomify.com/CVE-2026-48799/index.md","name":"CVE-2026-48799","record":{"aliases":["GHSA-j7rp-5mgj-qgg9"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["privilege_escalation","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Social media scheduling tool","requires_auth":"low_privilege","summary":"Attackers can grant lifetime PRO subscriptions to arbitrary organizations by bypassing payment verification in the Nowpayments webhook integration.","user_interaction":"not_required","vuln_class":"business_logic"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":7.7,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:N/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-639","name":"Authorization Bypass Through User-Controlled Key"},{"id":"CWE-345","name":"Insufficient Verification of Data Authenticity"}],"description":"Postiz is an AI social media scheduling tool.
