Exploitation Conditions

Exploitation requires that the target user is a local account (the product's own authentication, as opposed to LDAP/AD-backed accounts) and that the attacker can reach the Team Password Manager web application's password-reset endpoint over the network. Per CVSS AV:N/AC:L/AT:N/PR:N/UI:N, no authentication, no user interaction, and no special attack requirement are needed against a reachable instance running a version before 14.184.308. The primary limiting factors are network reachability of the instance (an internet-exposed deployment is fully exposed; an internal-only/VPN-gated one is not) and the use of local accounts - installations that authenticate users exclusively via an external directory may not present the vulnerable local-reset path to the same degree.

Impact

This is a genuinely high-priority issue rather than an inflated CVSS. The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H, score 9.3) describes network-reachable, low-complexity, unauthenticated exploitation with no user interaction and high confidentiality and integrity impact - all consistent with the description of an unauthenticated reset yielding account takeover. Availability is rated none (VA:N), which fits: the attack grants access rather than causing outage. No EPSS score, KEV entry, or SSVC decision data was provided, so probability of exploitation cannot be quantified from the input; the absence of KEV means no confirmed active exploitation, and no POC is referenced. The dominant risk driver is the product's purpose - it is a credential store - so a takeover cascades into downstream secret disclosure. The signals (unauth network vector, low complexity, credential-vault target) align without contradiction; the main uncertainty is real-world exploitation likelihood, which is unmeasured here.

Exploit ScenarioDerived

An attacker who can reach the Team Password Manager web interface over the network sends a crafted request to the local-account password-reset endpoint for a known or enumerated username, without authenticating. The server sets the attacker-chosen password because the identity-verification step is not enforced, and the attacker then logs in as that user and reads the shared vault entries visible to them. No public exploit code is referenced, but the low-complexity, no-interaction vector makes exploitation straightforward once the endpoint is reachable.

AnalysisAIv1 – Sep 02, 2026

Authentication bypass in Team Password Manager before 14.184.308 lets unauthenticated remote attackers abuse the local account password-reset flow to set arbitrary passwords for existing local users and then log in as them. Because this product is a self-hosted vault storing credentials for entire teams, a successful reset yields full account takeover and access to whatever secrets the victim can view. No public exploit has been identified at time of analysis, though the flaw was reported by VulnCheck and a fixed release is available.

RemediationAI

Vendor-released patch: upgrade to Team Password Manager 14.184.308 or later, which corrects the authentication enforcement in the local account password-reset flow; see the vendor changelog (https://teampasswordmanager.com/docs/changelog/) and release announcement (https://teampasswordmanager.com/blog/chrome-extension-6.42.27-tpm-14.184.308/). Until the upgrade is applied, restrict network exposure of the application by placing it behind a VPN or IP allowlist and limiting reachability of the login/reset endpoints to trusted networks, which reduces unauthenticated attacker access at the cost of remote convenience for legitimate users. Where feasible, prefer directory-backed (LDAP/AD) authentication over local accounts and monitor application logs for unexpected password-reset activity so that any takeover attempt can be detected and reset. Rotate credentials for any local accounts you suspect may have been targeted before patching.

Technical ContextAI · show details

Team Password Manager is a self-hosted, web-based (PHP/MySQL) shared password vault used by teams to store and share credentials. The root cause is CWE-640 (Weak Password Recovery Mechanism): the password-reset workflow for local accounts does not enforce the authentication/identity-verification step that should gate a reset, so the server accepts a reset for a targeted local user without proving the requester controls that account. This differs from LDAP/AD-backed accounts; the flaw is specific to the product's own 'local account' authentication mode. References point to the vendor site, the 14.184.308 changelog/blog, and the VulnCheck advisory rather than to a code diff, so the exact internal mechanism (e.g., unverified reset token, missing ownership check) is not disclosed in the input.

DescriptionCVE.org

Team Password Manager before 14.184.308 fails to enforce authentication requirements in the local account password reset flow. Unauthenticated attackers can reset local account passwords and authenticate as those users to gain unauthorized access.

Executive ViewAI

Why It Matters

Team Password Manager versions before 14.184.308 contain an authentication bypass that allows unauthenticated remote attackers to reset local user passwords and assume full account control. This directly compromises the core function of the product as an organization-wide credential vault, granting attackers access to all secrets managed by compromised accounts and potentially exposing credentials for critical infrastructure and systems.

Business Impact: Severe
Compensating Controls

Apply vendor patch to version 14.184.308 or later.
