It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-32723 exists.\n\nAffected packages and fixed versions:\n- @nyariv/sandboxjs (npm): affected all versions; fixed in 0.8.35\n- @nyariv/sandboxjs (npm): affected all versions; fixed in 0.8.35\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-2026-32723/ (Markdown: https://insights.sbomify.com/CVE-2026-32723/index.md)","id":"CVE-2026-32723","markdown":"https://insights.sbomify.com/CVE-2026-32723/index.md","name":"CVE-2026-32723","record":{"aliases":["GHSA-7p5m-xrh7-769r"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"JavaScript sandboxing library","requires_auth":"low_privilege","summary":"Attackers can bypass execution quotas in SandboxJS by exploiting a race condition in shared timer state, allowing resource exhaustion or quota evasion.","user_interaction":"not_required","vuln_class":"race_condition"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"sandboxjs","vendor":"nyariv"}],"cvss":{"score":4.8,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-362","name":"Concurrent Execution using Shared Resource with Improper Synchronization"}],"description":"SandboxJS is a JavaScript sandboxing library. Prior to 0.8.35, SandboxJS timers have an execution-quota bypass. A global tick state (`currentTicks.current`) is shared between sandboxes. Timer string handlers are compiled at execution time using that global tick state rather than the scheduling sandbox's tick object. In multi-tenant / concurrent sandbox scenarios, another sandbox can overwrite `currentTicks.current` between scheduling and execution, causing the timer callback to run under a different sandbox's tick budget and bypass the original sandbox's execution quota/watchdog. Version 0.8.35 fixes this issue.","ecosystems":["npm"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"SandboxJS timers have an execution-quota bypass (cross-sandbox currentTicks race)","id":"CVE-2026-32723","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"race_condition","year":"2026"},"n_packages":2,"n_references":2,"next":{"headline":"PX4 autopilot has a heap Use-After-Free in MavlinkShell::available() via SERIAL_CONTROL Race Condition","id":"CVE-2026-32724"},"packages":[{"ecosystem":"npm","fixed":["0.8.35"],"introduced":["0"],"last_affected":[],"package":"@nyariv/sandboxjs","purl":null,"source":"GHSA-7p5m-xrh7-769r"},{"ecosystem":"npm","fixed":["0.8.35"],"introduced":["0"],"last_affected":[],"package":"@nyariv/sandboxjs","purl":"pkg:npm/%40nyariv/sandboxjs","source":"GHSA-7p5m-xrh7-769r"}],"prev":{"headline":"Memray-generated HTML reports vulnerable to Stored XSS via unescaped command-line metadata","id":"CVE-2026-32722"},"products":["SandboxJS"],"published":"2026-03-18","related":[{"cvss_score":10,"headline":"SandboxJS: Sandbox escape via Function.caller leakage of internal call op","id":"CVE-2026-43898","kev_date_added":null,"published":"2026-05-28"},{"cvss_score":10,"headline":"SandboxJS: Sandbox integrity escape","id":"CVE-2026-34208","kev_date_added":null,"published":"2026-04-06"},{"cvss_score":10,"headline":"SandboxJS has a Sandbox Escape","id":"CVE-2026-26954","kev_date_added":null,"published":"2026-03-13"},{"cvss_score":10,"headline":"SandboxJS has a Sandbox Escape","id":"CVE-2026-25520","kev_date_added":null,"published":"2026-02-06"},{"cvss_score":10,"headline":"SandboxJS has a Sandbox Escape via Prototype Whitelist Bypass and Host Prototype Pollution","id":"CVE-2026-25586","kev_date_added":null,"published":"2026-02-06"},{"cvss_score":10,"headline":"SandboxJS has a Sandbox Escape","id":"CVE-2026-25587","kev_date_added":null,"published":"2026-02-06"},{"cvss_score":10,"headline":"SandboxJS has a sandbox escape via TOCTOU bug on keys in property accesses","id":"CVE-2026-25641","kev_date_added":null,"published":"2026-02-06"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"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":"2026-03-19","vendors":["nyariv"]},"summary":"Attackers can bypass execution quotas in SandboxJS by exploiting a race condition in shared timer state, allowing resource exhaustion or quota evasion.","url":"https://insights.sbomify.com/CVE-2026-32723/"}
