An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-53953 exists.\n\nAffected product: GetSimpleCMS-CE. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2026-53953/ (Markdown: https://insights.sbomify.com/CVE-2026-53953/index.md)","id":"CVE-2026-53953","markdown":"https://insights.sbomify.com/CVE-2026-53953/index.md","name":"CVE-2026-53953","record":{"aliases":["GHSA-vvhx-56q2-gcjq"],"analysis":{"component_type":"web_application","fix_type":"no_fix_stated","impacts":["account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"GetSimple CMS","requires_auth":"none","summary":"Attackers can predict temporary passwords due to weak random number generation, enabling administrator account takeover via brute-force attacks.","user_interaction":"not_required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":9.1,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-640","name":"Weak Password Recovery Mechanism for Forgotten Password"},{"id":"CWE-338","name":"Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG)"}],"description":"GetSimple CMS is a content management system (CMS), and GetSimple CMS CE is the community edition of that CMS. In version 3.3.22, the password reset endpoint can be accessed without authentication. When a reset request is submitted for an existing user, the application generates a new temporary password and immediately stores its hash as the user's new password. The temporary password is generated using PHP rand() seeded with microtime(). Because this seed is time-based and has a limited effective search space, an attacker can generate possible reset password candidates. Since the admin login endpoint does not enforce rate limiting or account lockout, these candidates can be tested online until the correct password is found. Successful exploitation may lead to administrator account takeover. At time of publication, there are no publicly available patches.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":false,"headline":"GetSimple CMS: Predictable Password Reset Password Allows Administrator Account Takeover","id":"CVE-2026-53953","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"weak_cryptography","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Bugsink: DOS using large numbers of event tags","id":"CVE-2026-53954"},"packages":[],"prev":{"headline":"GetSimple CMS \u0026 GetSimpleCMS-CE have an Unauthenticated Admin Account Creation via Setup Logic Flaw","id":"CVE-2026-53952"},"products":["GetSimpleCMS-CE"],"published":"2026-10-01","related":[],"sources":[{"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":"yes","exploitation":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-10-05","vendors":["GetSimpleCMS-CE"]},"summary":"Attackers can predict temporary passwords due to weak random number generation, enabling administrator account takeover via brute-force attacks.","url":"https://insights.sbomify.com/CVE-2026-53953/"}
