Descripción técnica

Use of Password Hash With Insufficient Computational Effort vulnerability in danielberkompas cloak_ecto and danielberkompas cloak allows an attacker who holds the hashed values and the configured secret to brute-force low-entropy plaintexts much faster than configured. The dump/1 callback that Cloak.Ecto.PBKDF2 (Cloak.Fields.PBKDF2 in cloak before the Ecto code moved to cloak_ecto) injects into a field module calls :pbkdf2.pbkdf2/4 with config[:size] in the iteration-count position. The :iterations setting is validated but never used. With the cloak_ecto defaults (iterations: 600_000, size: 32) each hash runs 32 PBKDF2 rounds instead of 600,000, so offline guessing of values such as email addresses costs about 18,750 times less than configured. This issue affects cloak_ecto: from 1.0.0-alpha.0 onward; cloak: from 0.7.0 before 1.0.0-alpha.0.

——6Xxyopen novel through 3.5.0 contains a weak password hashing vulnerability that allows attackers to recover plaintext passwords because UserServiceImpl.register() stores unsalted MD5 digests in user_info.password. Attackers who obtain the password column through a database leak or backup exposure can crack hashes with precomputed tables or GPU brute force and reuse credentials.2d CVE-2026-623768.1 ALT

——3Vikunja is an open-source self-hosted task management platform. Versions prior to 2.4.0 store password-reset, email-confirmation, and account-deletion tokens in the `user_tokens` table in plaintext. If an attacker gains read access to the database through a backup leak, misconfigured storage, or SQL-level exposure, they can immediately use pending tokens to take over user accounts without knowing passwords. Version 2.4.0 fixes the issue.2d CVE-2026-1078295.9 MED

——3Jivejdon through 5.0 contains a weak password storage vulnerability that stores account passwords as unsalted MD5 digests via ToolsUtil.hash() in AccountDaoSql. Attackers who obtain the user table through database access or SQL injection can crack passwords with precomputed tables or GPU attacks.1d CVE-2026-105804—

——0Payload is a free and open source headless content management system. Payload versions from 3.0.0 before 3.90.0 and canary versions from 4.0.0-canary.0 before 4.0.0-canary.34 use a lower-than-recommended PBKDF2 work factor for password hashing, reducing the computational effort required to test recovered password hashes. This issue is fixed in versions 3.90.0 and 4.0.0-canary.34.9d CVE-2026-1051563.7 BAJ

——2A weakness has been identified in YzmCMS up to 7.6. Impacted is the function Password of the file /common/function/system.func.php of the component MD5 Handler. Executing a manipulation of the argument pass can lead to password hash with insufficient computational effort. The attack may be launched remotely. This attack is characterized by high complexity. The exploitability is considered difficult. The exploit has been made available to the public and could be used for attacks. The vendor kindly explains: "Our regular release cycle is about 6 months. The last release was in the previous month, and our next scheduled version will be released in March 2027. We will implement the backward-compatible gradual hash migration feature in this upcoming release. (...) Before the new version is available, we will publish security mitigation guidance on our official documentation for existing deployers to reduce the risk."9d CVE-2026-854979.8 CRÍ

——8CareCam CM2507 IP cameras store the device's root-account password using a fixed legacy password hash that provides insufficient resistance to offline cracking. An attacker who obtains the firmware image or password database could recover the associated credential, which may also be reusable across other devices running the same firmware.24d
