Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-79775 exists.\n\nAffected packages and fixed versions:\n- rclone (Bitnami): affected from 1.72.0; fixed in 1.75.0\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/CVE-2026-79775/ (Markdown: https://insights.sbomify.com/CVE-2026-79775/index.md)","id":"CVE-2026-79775","markdown":"https://insights.sbomify.com/CVE-2026-79775/index.md","name":"CVE-2026-79775","record":{"aliases":["BIT-rclone-2026-79775","DEBIAN-CVE-2026-79775","GHSA-6jcg-q3wp-x2f4","GHSA-hqq5-m7fp-mqc3","MINI-c4pw-vg4w-7g26","MINI-xfc9-gpwm-rfgm","UBUNTU-CVE-2026-79775"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"rclone file sync tool","requires_auth":"low_privilege","summary":"Attackers can crash rclone or its SFTP server by providing malicious SquashFS images, causing denial of service via parser errors.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-129","name":"Improper Validation of Array Index"}],"description":"rclone versions \u003e= v1.72.0 and \u003c= v1.74.4 (fixed in v1.75.0) contain multiple denial-of-service vulnerabilities in the archive backend's SquashFS parser, which relies on the github.com/diskfs/go-diskfs dependency. The parser fails to validate attacker-controlled superblock and metadata values before use. An attacker who can place or modify a SquashFS image in storage exposed through an rclone :archive: remote can craft a malicious image that triggers an integer division-by-zero panic (zero block size), an out-of-bounds slice panic (out-of-range inode metadata offset), or a non-progress CPU loop (truncated metadata stream). Variants 1 and 2 terminate the rclone process and, via 'rclone serve sftp', can crash the entire SFTP server; variant 3 causes sustained CPU consumption. Parsing is lazy, so a victim or remote client must address or descend into the malicious archive object to trigger it.","ecosystems":["Bitnami"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"rclone Archive Backend SquashFS Parser Denial of Service","id":"CVE-2026-79775","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":1,"n_references":2,"next":{"headline":"rclone before 1.75.0 Authentication Bypass via pprof","id":"CVE-2026-79776"},"packages":[{"ecosystem":"Bitnami","fixed":["1.75.0"],"introduced":["1.72.0"],"last_affected":[],"package":"rclone","purl":"pkg:bitnami/rclone","source":"BIT-rclone-2026-79775"}],"prev":{"headline":"Winter CMS before 1.2.13 Twig Sandbox Escape via SecurityPolicy","id":"CVE-2026-79774"},"products":["rclone"],"published":"2026-08-25","related":[],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"Bitnami","prefix":"BIT"},{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-08-29","vendors":["rclone"]},"summary":"Attackers can crash rclone or its SFTP server by providing malicious SquashFS images, causing denial of service via parser errors.","url":"https://insights.sbomify.com/CVE-2026-79775/"}
