CVE-2026-35193 (GCVE-0-2026-35193)

Title
Potential exposure of private data via missing Vary: Authorization in UpdateCacheMiddleware
Summary
An issue was discovered in Django 5.2 before 5.2.15 and 6.0 before 6.0.6. `django.middleware.cache.UpdateCacheMiddleware` in Django does not add `Authorization` to the `Vary` response header for requests bearing that header without `Cache-Control: public`, which allows remote attackers to read private cached responses via unauthenticated requests to the same URL. Earlier, unsupported Django series (such as 5.0.x, 4.1.x, and 3.2.x) were not evaluated and may also be affected. Django would like to thank Shai Berger for reporting this issue.

Title
Discourse: Cached outdated summaries can leak removed content
Summary
Discourse is an open-source discussion platform. In versions prior to 2026.1.4, 2026.3.1, 2026.4.1 and 2026.5.0-latest.1, outdated cached AI summaries can leak removed content to anonymous and unprivileged users who cannot regenerate summaries. This issue has been fixed in versions 2026.1.4, 2026.3.1, 2026.4.1 and 2026.5.0-latest.1. To work around this issue, restrict summary generation by tightening the allowed groups on the summarization Personas.

CVE-2026-27205 (GCVE-0-2026-27205)

Title
Flask session does not add `Vary: Cookie` header when accessed in some ways
Summary
Flask is a web server gateway interface (WSGI) web application framework. In versions 3.1.2 and below, when the session object is accessed, Flask should set the Vary: Cookie header., resulting in a Use of Cache Containing Sensitive Information vulnerability. The logic instructs caches not to cache the response, as it may contain information specific to a logged in user. This is handled in most cases, but some forms of access such as the Python in operator were overlooked. The severity and risk depend on the application being hosted behind a caching proxy that doesn't ignore responses with cookies, not setting a Cache-Control header to mark pages as private or non-cacheable, and accessing the session in a way that only touches keys without reading values or mutating the session. The issue has been fixed in version 3.1.3.

Title
Mastodon's signature-dependent ActivityPub collection responses cached under signature-independent keys (Web Cache Poisoning via `Rails.cache`)
Summary
Mastodon is a free, open-source social network server based on ActivityPub. Prior to versions 4.3.19, 4.4.13, 4.5.6, Mastodon is vulnerable to web cache poisoning via `Rails.cache. When AUTHORIZED_FETCH is enabled, the ActivityPub endpoints for pinned posts and featured hashtags have contents that depend on the account that signed the HTTP request. However, these contents are stored in an internal cache and reused with no regards to the signing actor. As a result, an empty response generated for a blocked user account may be served to requests from legitimate non-blocked actors, or conversely, content intended for non-blocked actors may be returned to blocked actors. This issue has been patched in versions 4.3.19, 4.4.13, 4.5.6.

When AUTHORIZED_FETCH is enabled, the ActivityPub endpoints for pinned posts and featured hashtags have contents that depend on the account that signed the HTTP request. However, these contents are stored in an internal cache and reused with no regards to the signing actor. As a result, an empty response generated for a blocked user account may be served to requests from legitimate non-blocked actors, or conversely, content intended for non-blocked actors may be returned to blocked actors. This issue has been patched in versions 4.3.19, 4.4.13, 4.5.6."

CVE-2026-24472 (GCVE-0-2026-24472)

Vulnerability from cvelistv5 – Published: 2026-01-27 19:34 – Updated: 2026-01-27 20:52

Title
Hono cache middleware ignores "Cache-Control: private" leading to Web Cache Deception
Summary
Hono is a Web application framework that provides support for any JavaScript runtime. Prior to version 4.11.7, Cache Middleware contains an information disclosure vulnerability caused by improper handling of HTTP cache control directives. The middleware does not respect standard cache control headers such as `Cache-Control: private` or `Cache-Control: no-store`, which may result in private or authenticated responses being cached and subsequently exposed to unauthorized users. Version 4.11.7 has a patch for the issue.

CVE-2026-22741 (GCVE-0-2026-22741)

Title
Static resource cache poisoning in Spring MVC and WebFlux
Summary
Spring MVC and WebFlux applications are vulnerable to cache poisoning when resolving static resources. More precisely, an application can be vulnerable when all the following are true: * the application is using Spring MVC or Spring WebFlux * the application is configuring the  resource chain support https://docs.spring.io/spring-framework/reference/web/webmvc/mvc-config/static-resources.html#page-title  with caching enabled * the application adds support for encoded resources resolution * the resource cache must be empty when the attacker has access to the application When all the conditions above are met, the attacker can send malicious requests and poison the resource cache with resources using the wrong encoding. This can cause a denial of service by breaking the front-end application for clients.

Title
Insecure Public Caching on REST API Endpoints in Tenable Identity Exposure
Summary
Tenable Identity Exposure contains multiple unauthenticated API endpoints under /w/api/* that expose sensitive application configuration data including cleartext LDAP credentials, SAML configuration, user accounts, and directory settings to unauthenticated remote attackers. Affected responses are served with Cache-Control: public headers and without Vary: Cookie, allowing reverse proxies and CDNs to cache and serve sensitive data to unauthenticated users even after authentication is applied.

CVE-2026-9678 (GCVE-0-2026-9678)

Vulnerability from cvelistv5 – Published: 2026-06-17 17:04 – Updated: 2026-06-17 18:05

Title
undici vulnerable to cross-user information disclosure via shared cache whitespace bypass
Summary
Impact: Undici's cache interceptor incorrectly classifies some responses as cacheable when the upstream Cache-Control header uses whitespace-padded qualified private or no-cache field names such as private=" authorization" or no-cache="\tauthorization". The parser preserves the surrounding whitespace, so later comparisons against the literal authorization field name fail and the response is stored. In shared-cache mode, this allows a response containing one user's authenticated data to be served from cache to a subsequent caller, including an unauthenticated caller, when both requests resolve to the same cache key. Affected applications are those that explicitly enable the cache interceptor (interceptors.cache()) in shared mode, forward Authorization headers upstream, and receive cacheable responses with non-canonical qualified private or no-cache directives. Patches: Upgrade to undici v7.28.0 or v8.5.0. Workarounds: If upgrade is not immediately possible, disable shared-cache mode for traffic that includes Authorization headers, avoid caching responses to authenticated requests, or add Vary: Authorization upstream.

Title
Potential exposure of private data due to incorrect handling of Vary: * in UpdateCacheMiddleware
Summary
An issue was discovered in 6.0 before 6.0.5 and 5.2 before 5.2.14. `django.middleware.cache.UpdateCacheMiddleware` erroneously caches requests where the `Vary` header contained an asterisk (`'*'`). This can lead to private data being stored and served. Earlier, unsupported Django series (such as 5.0.x, 4.1.x, and 3.2.x) were not evaluated and may also be affected. Django would like to thank Ahmad Sadeddin for reporting this issue.

Architecture and Design

Consider using encryption in the cache.

CAPEC-204: Lifting Sensitive Data Embedded in Cache

An adversary examines a target application's cache, or a browser cache, for sensitive information. Many applications that communicate with remote entities or which perform intensive calculations utilize caches to improve efficiency. However, if the application computes or receives sensitive information and the cache is not appropriately protected, an attacker can browse the cache and retrieve this information. This can result in the disclosure of sensitive information.
