Harbor through 2.15.2 can disclose scanner adapter AccessCredential secrets to an authenticated project administrator who abuses fuzzy q-parameter filtering and observes response row counts one character at a time. This is a privilege-gated confidentiality issue rather than a critical remote-takeover flaw: the attacker must already hold a project-admin role and must issue many sequential API requests, with no user interaction and no special feature toggle required in default configurations. Publicly available exploit code exists, and the supplied data does not confirm active exploitation by CISA KEV.
GoHarbor Harbor versions 2.15.0 and earlier contain hardcoded default credentials that allow unauthenticated attackers to gain administrative access to the web UI using the default username 'admin' and password 'Harbor12345'. This vulnerability enables complete compromise of the container registry, including image manipulation, deletion, and unauthorized access to stored artifacts. The issue has been documented in GitHub issues and pull requests within the Harbor project, indicating active awareness and remediation efforts by the development team.
A wide range of Harbor versions allow SSRF via its webhook delivery component which does not properly validate web hook target addresses, allowing usage of private and link-local IP ranges. An authenticated attacker with ProjectAdmin permissions can configure a webhook policy pointing to a private internal address. When a project event fires, Harbor jobservice makes unauthenticated outbound HTTP POST requests to the target. If the target answers with an error status, the response body is written to the webhook execution log, which project members can read, potentially exposing cloud metadata or other network-restricted resources.
Incorrect user permission validation in Harbor <v2.9.5 and Harbor <v2.10.3 allows authenticated users to modify configurations. Rated medium severity (CVSS 4.3), this vulnerability is remotely exploitable, low attack complexity. No vendor patch available.
SQL-Injection in Harbor allows priviledge users to leak the task IDs. Rated medium severity (CVSS 5.5), this vulnerability is remotely exploitable, low attack complexity. No vendor patch available.
Open Redirect in Harbor <=v2.8.4, <=v2.9.2, and <=v2.10.0 may redirect a user to a malicious site. Rated medium severity (CVSS 6.1), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.
A timing condition in Harbor 2.6.x and below, Harbor 2.7.2 and below, Harbor 2.8.2 and below, and Harbor 1.10.17 and below allows an attacker with network access to create jobs/stop job tasks and. Rated medium severity (CVSS 6.5), this vulnerability is remotely exploitable, no authentication required. Public exploit code available and no vendor patch available.
Harbor 1.9.* 1.10.* and 2.0.* allows Exposure of Sensitive Information to an Unauthorized Actor. Rated medium severity (CVSS 4.3), this vulnerability is remotely exploitable, low attack complexity. Public exploit code available and no vendor patch available.
Harbor prior to 2.0.1 allows SSRF with this limitation: an attacker with the ability to edit projects can scan ports of hosts accessible on the Harbor server's intranet. Rated medium severity (CVSS 4.3), this vulnerability is remotely exploitable, low attack complexity. Public exploit code available and no vendor patch available.
A User Enumeration flaw exists in Harbor. Rated medium severity (CVSS 4.3), this vulnerability is remotely exploitable, low attack complexity. This Improper Privilege Management vulnerability could allow attackers to escalate privileges to gain unauthorized elevated access.
Harbor API has a Broken Access Control vulnerability. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. This Incorrect Default Permissions vulnerability could allow attackers to access resources due to overly permissive default settings.
core/api/user.go in Harbor 1.7.0 through 1.8.2 allows non-admin users to create admin accounts via the POST /api/users API, when Harbor is setup with DB as authentication backend and allow user to do. Rated medium severity (CVSS 6.5), this vulnerability is remotely exploitable, low attack complexity. This Missing Authorization vulnerability could allow attackers to access resources or perform actions without proper authorization checks.
The Ping() function in ui/api/target.go in Harbor through 1.3.0-rc4 has SSRF via the endpoint parameter to /api/targets/ping. Rated high severity (CVSS 8.6), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available and no vendor patch available.
