Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-49245 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/drakkan/sftpgo/v2 (Go): affected from 2.2.0; fixed in 2.7.3\n- github.com/drakkan/sftpgo/v2 (Go): affected from 2.2.0; fixed in 2.7.3\n- github.com/drakkan/sftpgo/v2 (Go): affected from 2.2.0; fixed in 2.7.3\n- github.com/drakkan/sftpgo (Go): affected all versions; no fix listed\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-2026-49245/ (Markdown: https://insights.sbomify.com/CVE-2026-49245/index.md)","id":"CVE-2026-49245","markdown":"https://insights.sbomify.com/CVE-2026-49245/index.md","name":"CVE-2026-49245","record":{"aliases":["GHSA-3vcg-pv95-pq54","GO-2026-5900"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"SFTPGo file transfer","requires_auth":"low_privilege","summary":"Attackers can execute arbitrary scripts in victims' browsers via stored XSS in SFTPGo public shares and user downloads.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":3.7,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"SFTPGo is an open source, event-driven file transfer solution. From 2.2.0 until 2.7.3, the inline query parameter on browsable-share file downloads and authenticated user-file downloads suppresses Content-Disposition: attachment, allowing an attacker-controlled HTML file stored in a share or home directory to be served as text/html in the SFTPGo web origin. An attacker who can place the file can send a crafted link to a victim, and opening that link executes the stored content in the victim's browser context.
