An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of GHSA-fxc9-7j2w-vx54 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- mpp (crates.io): affected all versions; fixed in 0.8.0\n- mpp (crates.io): affected all versions; fixed in 0.8.0\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/GHSA-fxc9-7j2w-vx54/ (Markdown: https://insights.sbomify.com/GHSA-fxc9-7j2w-vx54/index.md)","id":"GHSA-fxc9-7j2w-vx54","markdown":"https://insights.sbomify.com/GHSA-fxc9-7j2w-vx54/index.md","name":"GHSA-fxc9-7j2w-vx54","record":{"aliases":[],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_modify","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Rust payment library","requires_auth":"none","summary":"Attackers can bypass payment checks, replay transactions, and manipulate fee payers in the mpp library, leading to financial loss and service abuse.","user_interaction":"not_required","vuln_class":"business_logic"},"analysis_generated_by":"qwen3.8-flash-next","assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"### Impact\nMultiple vulnerabilities were discovered which allowed for undesirable behaviors, including:\n- Performing free `tempo/charge` requests\n- Replaying existing `tempo/charge` requests\n- Performing free `tempo/session` requests\n- Piggybacking off existing `tempo/session` channels\n- Griefing existing `tempo/session` channels\n- Manipulate the fee payer of a `tempo/charge` or `tempo/session` handler into paying for requests\n- Replaying existing `stripe/charge` requests\n\n### Patches\nThe issues are patched in 0.8.0\n\n### Workarounds\nThere are no workarounds available for these vulnerabilities","ecosystems":["crates.io"],"exploits":{"exploitdb":null,"first_seen":null,"github_poc":null,"max_poc_stars":null,"metasploit":null,"nuclei":null,"refs":[],"tier":null},"has_fix":true,"headline":"mpp has multiple payment bypass and griefing vulnerabilities","id":"GHSA-fxc9-7j2w-vx54","indexable":true,"kev":null,"kind":"advisory","links":{"ecosystem":"crates.io","product":null,"products":[],"type":"business_logic","year":"2026"},"n_packages":2,"n_references":null,"packages":[{"ecosystem":"crates.io","fixed":["0.8.0"],"introduced":["0"],"last_affected":[],"package":"mpp","purl":null,"source":"GHSA-fxc9-7j2w-vx54"},{"ecosystem":"crates.io","fixed":["0.8.0"],"introduced":["0"],"last_affected":[],"package":"mpp","purl":"pkg:cargo/mpp","source":"GHSA-fxc9-7j2w-vx54"}],"products":null,"published":"2026-03-29","related":[],"sources":[{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":null,"updated":null,"vendors":null},"summary":"Attackers can bypass payment checks, replay transactions, and manipulate fee payers in the mpp library, leading to financial loss and service abuse.","url":"https://insights.sbomify.com/GHSA-fxc9-7j2w-vx54/"}
