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-2025-53633 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/ctfer-io/chall-manager (Go): affected all versions; fixed in 0.1.4\n- github.com/ctfer-io/chall-manager (Go): affected all versions; fixed in 0.1.4\n- github.com/ctfer-io/chall-manager (Go): affected all versions; fixed in 0.1.4\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-2025-53633/ (Markdown: https://insights.sbomify.com/CVE-2025-53633/index.md)","id":"CVE-2025-53633","markdown":"https://insights.sbomify.com/CVE-2025-53633/index.md","name":"CVE-2025-53633","record":{"aliases":["GHSA-r7fm-3pqm-ww5w","GO-2025-3810"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"CTF challenge manager","requires_auth":"none","summary":"Unauthenticated attackers can cause denial of service via zip bomb decompression in Chall-Manager scenario decoding.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"chall-manager","vendor":"ctfer-io"}],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-405","name":"Asymmetric Resource Consumption (Amplification)"}],"description":"Chall-Manager is a platform-agnostic system able to start Challenges on Demand of a player.

Exploitation does not require authentication nor authorization, so anyone can exploit it. It should nonetheless not be exploitable as it is highly recommended to bury Chall-Manager deep within the infrastructure due to its large capabilities, so no users could reach the system.
