Vulnerability from cvelistv5 – Published: 2026-09-08 00:12 – Updated: 2026-09-08 10:34

Title

Credential disclosure in multitenant applications using SAP Cloud Application Programming Model (CAP)

Summary

@sap/cds-mtxs NPM library does not perform sufficient checks on certain functionality used in multitenant CAP applications with extensibility enabled. An unauthenticated attacker could send specially crafted requests to obtain sensitive credentials and abuse them to replace or delete tenant data. Successful exploitation can result in a high impact on availability and integrity of the application. There may also be partial impact to the confidentiality of business data.

Severity

9.4 (Critical)

CVE-2026-76846 (GCVE-0-2026-76846)

Vulnerability from cvelistv5 – Published: 2026-08-25 01:30 – Updated: 2026-08-27 14:55

Title

Grav before 2.0.16 Information Disclosure via Twig Sandbox

Summary

Grav before 2.0.16 contains an incomplete default denylist in the Twig sandbox configuration that fails to block access to system configuration secrets. Attackers with page-edit permission can use config.get() or config.toArray() in Twig templates to retrieve sensitive values like system.cache.redis.password when config_access is enabled.

CVE-2026-76839 (GCVE-0-2026-76839)

Vulnerability from cvelistv5 – Published: 2026-08-25 01:30 – Updated: 2026-08-25 15:45

Title

Grav before 2.0.16 Information Disclosure via offsetGet

Summary

Grav before 2.0.16 allows sandboxed Twig templates to access sensitive User fields through allow-listed offsetGet() and offsetexists() methods that lack field filtering. Attackers with page-edit permissions can call offsetGet() on User objects to extract hashed passwords and 2FA secrets, enabling offline password cracking and authentication bypass.

CVE-2026-75136 (GCVE-0-2026-75136)

Vulnerability from cvelistv5 – Published: 2026-09-02 19:15 – Updated: 2026-09-03 13:33

Title

UpSignOn < 7.19.0 Biometric Key Exposure via Windows PasswordVault

Summary

UpSignOn for Windows before 7.19.0 contains an insecure credential storage vulnerability that allows local attackers to retrieve the biometric unlock key stored in the Windows PasswordVault API without triggering any authentication prompt. Attackers can access the stored biometric key from a standard local process within the same Windows session to decrypt the protected vault files and export the entire password manager contents in cleartext.

Severity

6.9 (Medium)

CVE-2026-75015 (GCVE-0-2026-75015)

Vulnerability from cvelistv5 – Published: 2026-09-14 12:55 – Updated: 2026-09-14 19:26

Title

Apache Syncope: Nested secrets leak cleartext into audit records readable

Summary

Insufficiently Protected Credentials vulnerability in Apache Syncope. Audit events, when sent to the configured store, are not sufficiently masked for the sensitive values they might carry on their payloads, thus allowing administrators to access such sensitive values. This issue affects Apache Syncope: from 3.0.0-M0 through 3.0.16, from 4.0.0-M0 Through 4.0.7, from 4.1.0-M0 through 4.1.2. Users are recommended to upgrade to version 4.0.8 / 4.1.3, which fix this issue.

Severity

4.9 (Medium)

Mitigation

Architecture and Design

Use an appropriate security mechanism to protect the credentials.

Mitigation

Architecture and Design

Make appropriate use of cryptography to protect the credentials.

Mitigation

Implementation

Use industry standards to protect the credentials (e.g. LDAP, keystore, etc.).

CAPEC-102: Session Sidejacking

Session sidejacking takes advantage of an unencrypted communication channel between a victim and target system. The attacker sniffs traffic on a network looking for session tokens in unencrypted traffic. Once a session token is captured, the attacker performs malicious actions by using the stolen token with the targeted application to impersonate the victim. This attack is a specific method of session hijacking, which is exploiting a valid session token to gain unauthorized access to a target system or information. Other methods to perform a session hijacking are session fixation, cross-site scripting, or compromising a user or server machine and stealing the session token.

CAPEC-474: Signature Spoofing by Key Theft

An attacker obtains an authoritative or reputable signer's private signature key by theft and then uses this key to forge signatures from the original signer to mislead a victim into performing actions that benefit the attacker.

CAPEC-50: Password Recovery Exploitation

An attacker may take advantage of the application feature to help users recover their forgotten passwords in order to gain access into the system with the same privileges as the original user. Generally password recovery schemes tend to be weak and insecure.

CAPEC-509: Kerberoasting

Through the exploitation of how service accounts leverage Kerberos authentication with Service Principal Names (SPNs), the adversary obtains and subsequently cracks the hashed credentials of a service account target to exploit its privileges. The Kerberos authentication protocol centers around a ticketing system which is used to request/grant access to services and to then access the requested services. As an authenticated user, the adversary may request Active Directory and obtain a service ticket with portions encrypted via RC4 with the private key of the authenticated account. By extracting the local ticket and saving it disk, the adversary can brute force the hashed value to reveal the target account credentials.

CAPEC-551: Modify Existing Service

When an operating system starts, it also starts programs called services or daemons. Modifying existing services may break existing services or may enable services that are disabled/not commonly used.

CAPEC-555: Remote Services with Stolen Credentials

This pattern of attack involves an adversary that uses stolen credentials to leverage remote services such as RDP, telnet, SSH, and VNC to log into a system. Once access is gained, any number of malicious activities could be performed.

CAPEC-560: Use of Known Domain Credentials

An adversary guesses or obtains (i.e. steals or purchases) legitimate credentials (e.g. userID/password) to achieve authentication and to perform authorized actions under the guise of an authenticated user or service.

CAPEC-561: Windows Admin Shares with Stolen Credentials

An adversary guesses or obtains (i.e. steals or purchases) legitimate Windows administrator credentials (e.g. userID/password) to access Windows Admin Shares on a local machine or within a Windows domain.

CAPEC-600: Credential Stuffing

An adversary tries known username/password combinations against different systems, applications, or services to gain additional authenticated access. Credential Stuffing attacks rely upon the fact that many users leverage the same username/password combination for multiple systems, applications, and services.

CAPEC-644: Use of Captured Hashes (Pass The Hash)

An adversary obtains (i.e. steals or purchases) legitimate Windows domain credential hash values to access systems within the domain that leverage the Lan Man (LM) and/or NT Lan Man (NTLM) authentication protocols.

CAPEC-645: Use of Captured Tickets (Pass The Ticket)

An adversary uses stolen Kerberos tickets to access systems/resources that leverage the Kerberos authentication protocol. The Kerberos authentication protocol centers around a ticketing system which is used to request/grant access to services and to then access the requested services. An adversary can obtain any one of these tickets (e.g. Service Ticket, Ticket Granting Ticket, Silver Ticket, or Golden Ticket) to authenticate to a system/resource without needing the account's credentials. Depending on the ticket obtained, the adversary may be able to access a particular resource or generate TGTs for any account within an Active Directory Domain.

CAPEC-652: Use of Known Kerberos Credentials

An adversary obtains (i.e. steals or purchases) legitimate Kerberos credentials (e.g. Kerberos service account userID/password or Kerberos Tickets) with the goal of achieving authenticated access to additional systems, applications, or services within the domain.

CAPEC-653: Use of Known Operating System Credentials

An adversary guesses or obtains (i.e. steals or purchases) legitimate operating system credentials (e.g. userID/password) to achieve authentication and to perform authorized actions on the system, under the guise of an authenticated user or service. This applies to any Operating System.
