| Exploitation Conditions | Exploitation requires possession of a valid Artifactory integration credential - specifically the type used for programmatic/machine-to-machine access (e.g., access tokens issued to service accounts or CI/CD integrations). The CVSS PR:H metric confirms that elevated credential access is a hard prerequisite; unauthenticated remote exploitation is not possible. The description's phrase 'under specific conditions' introduces an additional environmental qualifier that is not fully specified in available data - it may refer to a particular token type, a specific Artifactory configuration (such as OAuth or SSO integration mode), or a specific API endpoint being targeted; this condition should be clarified via the vendor advisory. Exploitation is limited to: actors who already hold a valid integration credential, situations matching the unspecified 'specific conditions', and network access to the Artifactory instance. These limiting factors mean organizations with tightly controlled, individually scoped, and monitored integration credentials face materially lower risk than those with broadly shared or unmonitored tokens. |
| Impact | The CVSS base score of 7.2 (High) is driven by the full C:H/I:H/A:H impact triad paired with AV:N/AC:L/PR:H/UI:N. The PR:H requirement - a valid integration credential - is the primary risk limiter: unauthenticated internet adversaries cannot exploit this directly. However, integration credentials in enterprise environments are frequently embedded in CI/CD pipelines, shared across teams, or leaked through misconfigured secrets management, making PR:H a weaker barrier than it appears in isolation. The AC:L rating in the vendor vector slightly conflicts with the description's 'specific conditions' qualifier, which may imply environmental prerequisites that raise practical complexity. EPSS data was not provided, so exploitation probability cannot be quantified. No KEV listing and no public POC are confirmed, indicating no observed mass exploitation at time of analysis. The net risk is elevated for organizations with broad integration credential distribution or poor secrets hygiene, and reduced for those with tightly scoped, monitored service accounts. |
| Exploit ScenarioDerived | An attacker who has legitimately obtained or stolen an Artifactory integration credential - for example, a CI/CD bot token leaked from a misconfigured repository secret or build log - exploits the JWT signature verification flaw to craft a token that asserts the identity of a privileged user such as an administrator. The attacker then uses this forged token to authenticate to Artifactory's API, gaining full read/write/delete access to all repositories and administrative controls as that impersonated user. No public proof-of-concept has been identified at time of analysis, but the JWT attack class is well-documented and the technique is commonly known to adversaries. |

Alert meAnalysisAIv1 – Aug 12, 2026
JFrog Artifactory's JWT handling allows a holder of a valid integration credential to impersonate arbitrary users under specific conditions, exploiting an improper cryptographic signature verification flaw (CWE-347). Any actor in possession of a legitimate integration token - such as a CI/CD service account - can craft or manipulate JWT tokens to assume the identity of other users, including privileged ones, gaining their full access to repositories and administrative functions. No public exploit has been identified at time of analysis, and the vulnerability has not been added to the CISA KEV catalog; however, the full C:H/I:H/A:H CVSS impact profile warrants prompt patching in environments where integration credentials are broadly distributed.
RemediationAI
Consult the JFrog Security Advisories page (https://docs.jfrog.com/releases/docs/jfrog-security-advisories) and the Artifactory self-managed release notes (https://docs.jfrog.com/releases/docs/artifactory-self-managed-releases) to identify the specific fixed release and apply the vendor patch immediately - no exact fix version was provided in available intelligence and cannot be independently confirmed without reviewing those pages. As a compensating control prior to patching, audit and rotate all integration credentials, applying least-privilege scoping so that each service account is bound to a single repository or operation set; this limits the blast radius if a credential is used to impersonate another user. Additionally, enable Artifactory audit logging for authentication events and alert on any access token used from an unexpected IP, user agent, or at an unusual time, as impersonation will produce anomalous access patterns. Restricting integration credential permissions to read-only where write access is not required reduces the integrity and availability impact of exploitation. Note that credential rotation alone does not fix the underlying JWT verification flaw and must be combined with patching.

Technical ContextAI · show details
JFrog Artifactory (CPE: cpe:2.3:a:jfrog:artifactory:*:*:*:*:*:*:*:*) is an enterprise binary repository manager widely used in CI/CD pipelines. It supports integration credentials - machine-level tokens used by build systems, scanners, and automation tools - which authenticate via JWT (JSON Web Tokens). CWE-347 (Improper Verification of Cryptographic Signature) indicates the server fails to adequately validate the cryptographic integrity of JWT tokens presented by integration credential holders. In a correct implementation, a JWT signed with one identity's private material cannot be accepted as another user's token; however, a flaw in signature verification logic - such as accepting unsigned tokens (the 'alg:none' attack), failing to bind the token to the originating identity, or improperly trusting user-controlled claims - allows token forgery or substitution. The 'JWT Attack' tag in the source intelligence confirms this is the exploit class.

A holder of a valid integration credential may impersonate other users under specific conditions.
Executive ViewAI
JFrog Artifactory contains a JWT token handling vulnerability that allows any holder of a valid integration credential-including CI/CD service accounts-to impersonate administrative users and assume their full access to repositories and administrative functions. This represents a critical supply chain risk, as compromised or overly-permissioned service accounts could enable unauthorized artifact modification, repository access, or administrative takeover. The vulnerability's high impact across confidentiality, integrity, and availability demands immediate credential audit and access controls.
No vendor-released patch identified at time of analysis. Interim mitigations: (1) Strictly limit integration credential distribution and revoke any not actively in use; (2) Implement network segmentation restricting which systems can authenticate to Artifactory; (3) Enable comprehensive JWT and authentication event logging with real-time alerting on unusual token patterns; (4) Audit all integration accounts and remove those with unnecessary administrative privileges; (5) Require multi-factor authentication or certificate-based authentication for high-privilege accounts where Artifactory supports it; (6) Segment critical artifact repositories on isolated instances if feasible.
