| CVE-2025-52571 | Cri | 0.55 | 9.6 | 0.00 | Jun 24, 2025 | Hikka is a Telegram userbot. A vulnerability affects all users of versions below 1.6.2, including most of the forks. It allows an unauthenticated attacker to gain access to Telegram account of a victim, as well as full access to the server. The issue is patched in version 1.6.2. No known workarounds are available. | |
| CVE-2025-30215 | Cri | 0.55 | 9.6 | 0.00 | Apr 16, 2025 | NATS-Server is a High-Performance server for NATS.io, the cloud and edge native messaging system. In versions starting from 2.2.0 but prior to 2.10.27 and 2.11.1, the management of JetStream assets happens with messages in the $JS. subject namespace in the system account; this is partially exposed into regular accounts to allow account holders to manage their assets. Some of the JS API requests were missing access controls, allowing any user with JS management permissions in any account to perform certain administrative actions on any JS asset in any other account. At least one of the unprotected APIs allows for data destruction. None of the affected APIs allow disclosing stream contents. This vulnerability is fixed in v2.11.1 or v2.10.27. | |
| CVE-2017-1000106 | Hig | 0.55 | 8.5 | 0.00 | Oct 5, 2017 | Blue Ocean allows the creation of GitHub organization folders that are set up to scan a GitHub organization for repositories and branches containing a Jenkinsfile, and create corresponding pipelines in Jenkins. Its SCM content REST API supports the pipeline creation and editing feature in Blue Ocean. The SCM content REST API did not check the current user's authentication or credentials. If the GitHub organization folder was created via Blue Ocean, it retained a reference to its creator's GitHub credentials. This allowed users with read access to the GitHub organization folder to create arbitrary commits in the repositories inside the GitHub organization corresponding to the GitHub organization folder with the GitHub credentials of the creator of the organization folder. Additionally, users with read access to the GitHub organization folder could read arbitrary file contents from the repositories inside the GitHub organization corresponding to the GitHub organization folder if the branch contained a Jenkinsfile (which could be created using the other part of this vulnerability), and they could provide the organization folder name, repository name, branch name, and file name. | |
| CVE-2017-6104 | Hig | 0.55 | 7.5 | 0.39 | Mar 2, 2017 | Remote file upload vulnerability in Wordpress Plugin Mobile App Native 3.0. | |
| CVE-2026-41571 | Cri | 0.54 | 9.4 | 0.00 | May 4, 2026 | Note Mark is an open-source note-taking application. In version 0.19.2, IsPasswordMatch in backend/db/models.go falls back to a hard-coded bcrypt("null") placeholder whenever a user has no stored password. OIDC-registered users are created with an empty password, so anyone who submits password: "null" to the internal login endpoint receives a valid session for that user. The bypass is unauthenticated and requires no user interaction. This issue has been patched in version 0.19.3. | |
| CVE-2026-34072 | Hig | 0.54 | 8.3 | 0.00 | Apr 1, 2026 | Cr*nMaster (cronmaster) is a Cronjob management UI with human readable syntax, live logging and log history for cronjobs. Prior to version 2.2.0, an authentication bypass in middleware allows unauthenticated requests with an invalid session cookie to be treated as authenticated when the middleware’s session-validation fetch fails. This can result in unauthorized access to protected pages and unauthorized execution of privileged Next.js Server Actions. This issue has been patched in version 2.2.0. | |
| CVE-2025-59934 | Cri | 0.54 | 9.4 | 0.00 | Sep 26, 2025 | Formbricks is an open source qualtrics alternative. Prior to version 4.0.1, Formbricks is missing JWT signature verification. This vulnerability stems from a token validation routine that only decodes JWTs (jwt.decode) without verifying their signatures. Both the email verification token login path and the password reset server action use the same validator, which does not check the token’s signature, expiration, issuer, or audience. If an attacker learns the victim’s actual user.id, they can craft an arbitrary JWT with an alg: "none" header and use it to authenticate and reset the victim’s password. This issue has been patched in version 4.0.1. | |
| CVE-2024-7050 | Hig | 0.54 | — | 0.00 | Jul 26, 2024 | Improper Authentication vulnerability in OpenText OpenText Directory Services may allow Multi-factor Authentication Bypass in particular scenarios.This issue affects OpenText Directory Services: 24.2. | |
| CVE-2024-26331 | Hig | 0.54 | 7.5 | 0.68 | Apr 30, 2024 | ReCrystallize Server 5.10.0.0 uses a authorization mechanism that relies on the value of a cookie, but it does not bind the cookie value to a session ID. Attackers can easily modify the cookie value, within a browser or by implementing client-side code outside of a browser. Attackers can bypass the authentication mechanism by modifying the cookie to contain an expected value. | |
| CVE-2017-2319 | Hig | 0.54 | 8.3 | 0.01 | Apr 24, 2017 | A vulnerability in Juniper Networks NorthStar Controller Application prior to version 2.1.0 Service Pack 1 may allow a malicious attacker to compromise the systems confidentiality or integrity without authentication, leading to managed systems being compromised or services being denied to authentic end users and systems as a result. | |
| CVE-2016-6434 | Hig | 0.54 | 7.8 | 0.00 | Oct 6, 2016 | Cisco Firepower Management Center 6.0.1 has hardcoded database credentials, which allows local users to obtain sensitive information by leveraging CLI access, aka Bug ID CSCva30370. | |
| CVE-2015-7521 | Hig | 0.54 | 8.3 | 0.00 | Jan 29, 2016 | The authorization framework in Apache Hive 1.0.0, 1.0.1, 1.1.0, 1.1.1, 1.2.0 and 1.2.1, on clusters protected by Ranger and SqlStdHiveAuthorization, allows attackers to bypass intended parent table access restrictions via unspecified partition-level operations. | |

| CVE-2026-42602 | Hig | 0.53 | 8.1 | 0.00 | May 13, 2026 | azureauthextension is the Azure Authenticator Extension. From 0.124.0 to 0.150.0, a server-side authentication bypass in azureauthextension allows any party who holds a single valid Azure access token for any scope the collector's configured identity can mint for to authenticate to any OpenTelemetry receiver that uses auth: azure_auth. The extension's Authenticate method does not validate incoming bearer tokens as JWTs. Instead, it calls its own configured credential to obtain an access token and compares the client's token to the result with string equality — and the scope for that server-side token request is taken from the client-supplied Host header. As a result, a token minted for any Azure resource the service principal has ever been issued a token for (ARM, Graph, Key Vault, Storage, etc.) will authenticate to the collector if the attacker picks a matching Host. Tokens are replayable for the full issued lifetime (commonly several hours for managed identity tokens). | |
| CVE-2026-4101 | Hig | 0.53 | 8.1 | 0.00 | Apr 1, 2026 | IBM Verify Identity Access Container 11.0 through 11.0.2 and IBM Security Verify Access Container 10.0 through 10.0.9.1 and IBM Verify Identity Access 11.0 through 11.0.2 and IBM Security Verify Access 10.0 through 10.0.9.1 under certain load conditions could allow an attacker to bypass authentication mechanisms and gain unauthorized access to the application. | |
| CVE-2026-4021 | Hig | 0.53 | 8.1 | 0.00 | Mar 24, 2026 | The Contest Gallery plugin for WordPress is vulnerable to an authentication bypass leading to admin account takeover in all versions up to, and including, 28.1.5. This is due to the email confirmation handler in `users-registry-check-after-email-or-pin-confirmation.php` using the user's email string in a `WHERE ID = %s` clause instead of the numeric user ID, combined with an unauthenticated key-based login endpoint in `ajax-functions-frontend.php`. When the non-default `RegMailOptional=1` setting is enabled, an attacker can register with a crafted email starting with the target user ID (e.g., `1poc@example.test`), trigger the confirmation flow to overwrite the admin's `user_activation_key` via MySQL integer coercion, and then use the `post_cg1l_login_user_by_key` AJAX action to authenticate as the admin without any credentials. This makes it possible for unauthenticated attackers to take over any WordPress administrator account and gain full site control. | |
| CVE-2025-68402 | Hig | 0.53 | — | 0.00 | Mar 9, 2026 | FreshRSS is a free, self-hostable RSS aggregator. From 57e1a37 - 00f2f04, the lengths of the nonce was changed from 40 chars to 64. password_verify() is currently being called with a constructed string (SHA-256 nonce + part of a bcrypt hash) instead of the raw user password. Due to bcrypt’s 72-byte input truncation, this causes password verification to succeed even when the user enters an incorrect password. This vulnerability is fixed in 1.27.2-dev (476e57b). The issue was only present in the edge branch and never in a stable release. |
