CWE-208
AllowedObservable Timing Discrepancy
Abstraction: Base · Status: Incomplete
Two separate operations in a product require different amounts of time to complete, in a way that is observable to an actor and reveals security-relevant information about the state of the product, such as whether a particular operation was successful or not.
306 vulnerabilities reference this CWE, most recent first.

GHSA-9M89-8FRQ-C98C
Vulnerability from github – Published: 2026-05-12 18:30 – Updated: 2026-05-19 14:28Versions Affected: Apache Tomcat 11.0.0-M1 to 11.0.21 Apache Tomcat 10.1.0-M1 to 10.1.54 Apache Tomcat 9.0.0.M1 to 9.0.117 Older, unsupported versions may also be affected
Description: The AJP secret was compared in non-constant time allowing an attacker on the local network to mount a timing attack to determine the AJP secret.
Mitigation: Users of the affected versions should apply one of the following mitigations: - Upgrade to Apache Tomcat 11.0.22 or later - Upgrade to Apache Tomcat 10.1.55 or later - Upgrade to Apache Tomcat 9.0.118 or later

GHSA-C2FC-9Q9C-5486
Vulnerability from github – Published: 2025-09-17 20:02 – Updated: 2025-09-26 16:17Impact
The access control mechanism for the Proxy feature uses simple string comparisons and is therefore vulnerable to timing attacks. An attacker may try to guess the password one character at a time by sending all possible characters to a vulnerable mechanism and measuring the comparison instruction’s execution times. The vulnerability is shown in figure 8.1, where both the username and password are compared with a short-circuiting equality operation.
if user != proxy.basicAuth.Username || pass != proxy.basicAuth.Password {
It is currently undetermined what an attacker may be able to do with access to the proxy password.
Patches
- Dragonfy v2.1.0 and above.
Workarounds
There are no effective workarounds, beyond upgrading.

Vulnerability from github – Published: 2026-02-10 12:30 – Updated: 2026-02-10 14:33Observable Timing Discrepancy vulnerability in Apache Shiro.
This issue affects Apache Shiro: from 1., 2. before 2.0.7.
Users are recommended to upgrade to version 2.0.7 or later, which fixes the issue.
Prior to Shiro 2.0.7, code paths for non-existent vs. existing users are different enough, that a brute-force attack may be able to tell, by timing the requests only, determine if the request failed because of a non-existent user vs. wrong password.
The most likely attack vector is a local attack only. Shiro security model https://shiro.apache.org/security-model.html#username_enumeration discusses this as well.
Typically, brute force attack can be mitigated at the infrastructure level.

GHSA-C6WG-CM5X-RQVJ
Vulnerability from github – Published: 2023-03-07 17:38 – Updated: 2023-03-07 17:38Impact
There is an observable discrepancy in the authentication response time between calls where the user provided exists and calls where it does not. This issue only affects calls using the internal basic identity provider (IdP), and not other externally configured IdPs.
Patches
OpenSearch 1.3.9 and 2.6.0
Workarounds
None.

No mitigation information available for this CWE.
CAPEC-462: Cross-Domain Search Timing
An attacker initiates cross domain HTTP / GET requests and times the server responses. The timing of these responses may leak important information on what is happening on the server. Browser's same origin policy prevents the attacker from directly reading the server responses (in the absence of any other weaknesses), but does not prevent the attacker from timing the responses to requests that the attacker issued cross domain.
CAPEC-541: Application Fingerprinting
An adversary engages in fingerprinting activities to determine the type or version of an application installed on a remote target.
CAPEC-580: System Footprinting
An adversary engages in active probing and exploration activities to determine security information about a remote target system. Often times adversaries will rely on remote applications that can be probed for system configurations.
