Summary
Authentication Bypass by Capture-replay in Apache Roller 6.1.5 allows an attacker who captures a valid WSSE digest authentication header to replay it and gain the victim's AtomPub authority, because the authentication does not enforce nonce uniqueness or timestamp freshness.
Risk Assessment
An attacker can take over the victim's AtomPub authority and perform operations on their behalf, leading to unauthorized access to blog content and configuration.
Recommendation
Upgrade Apache Roller to version 6.1.6 or later, which removes WSSE as an AtomPub authentication method; existing WSSE-configured installations will fail closed until an administrator selects a supported method.
Other vulnerabilities in Apache Roller
See all- CVE-2026-86507Medium
Improper neutralization of input in Apache Roller 6.1.5 allows an anonymous remote attacker to store a crafted comment-author URL that can execute script in the session of a weblog moderator or global administrator when the comment management page is viewed. This affects sites that permit comments on at least one weblog and whose moderator subsequently reviews the submitted comment; no non-default server setting is required.
- CVE-2026-82383High
Missing Authentication for Critical Function in Apache Roller 6.1.5 allows an unauthenticated remote attacker to persistently change a site-global configuration value (the frontpage weblog selection) on any installed instance, because the setup action remains anonymously reachable after installation and persists configuration without an authorization check.
- CVE-2026-82382Medium
Reflected Cross-site Scripting (XSS) vulnerability in Apache Roller 6.1.5 allows a remote attacker to perform reflected cross-site scripting against a visitor to a weblog using the bundled frontpage theme, by supplying a crafted blog-directory parameter that the directory page reflects without proper escaping. Affects only weblogs using the bundled frontpage theme, and a victim must follow a crafted link.
- CVE-2026-82381Medium
Stored Cross-site Scripting (XSS) vulnerability in Apache Roller 6.1.5 allows a user with authoring rights on a weblog to store crafted content that is later written into the authoring UI's JavaScript string literals and markup sinks without proper encoding, causing the stored script to execute in another author's or administrator's browser. No optional feature or non-default configuration is required; affects weblogs with multiple authors or administrators who are not mutually trusted.
- CVE-2026-82380High
Cross-Site Request Forgery (CSRF) in Apache Roller 6.1.5 allows a remote attacker to cause a logged-in user to perform state-changing actions under the victim's authority, because the CSRF validation filters accept a request that does not submit the required salt token, validating instead against a value the server itself generated for the request.
- CVE-2026-82375High
Server-Side Request Forgery (SSRF) in Apache Roller 6.1.5 allows an authenticated user with entry-editing rights on a weblog to cause outbound HTTP requests to attacker-chosen destinations through legacy outbound Trackback and entry enclosure handling. The Trackback control is hidden in the standard UI, but its action remains directly reachable, and the default empty Trackback allow-list permits all destinations. Requests can reach loopback and private-network addresses.
- CVE-2015-0249High
The weblog page template in Apache Roller versions 5.1 through 5.1.1 allows remote authenticated users with admin privileges for a weblog to execute arbitrary Java code via crafted Velocity Text Language (aka VTL).
- CVE-2026-82384Critical
Apache Roller 6.1.5 contains a Deserialization of Untrusted Data vulnerability because the XML-RPC endpoint accepts vendor extension types that are deserialized during request parsing, before authentication. The servlet is mapped unconditionally, so parsing occurs even when the global XML-RPC feature is disabled; no non-default configuration is required. This can lead to remote code execution.
- CVE-2026-82378Critical
Apache Roller 6.1.5 contains an Incorrect Authorization vulnerability in the OAuth 1.0a authorization endpoint. An unauthenticated remote attacker who learns an outstanding request token for a configured site-wide consumer can bind that token to an arbitrary user account, including an administrator, by submitting an unsigned authorization request. The endpoint derives the authorizing identity from a request-supplied value rather than the authenticated session.
- CVE-2026-82377Critical
Apache Roller 6.1.5 contains a Missing Authorization vulnerability that allows an authenticated user to read, modify, or delete weblog content belonging to other weblogs through the legacy XML-RPC Blogger and MetaWeblog APIs. The handlers authenticate the caller but do not verify the caller's permission on the weblog or entry actually affected. Only installations that enable the non-default global XML-RPC setting are affected; the per-weblog API flag defaults to enabled for UI-created weblogs.
Original NVD description (English source)
Authentication Bypass by Capture-replay in Apache Roller 6.1.5 allows an attacker who captures a valid WSSE digest authentication header to replay it and gain the victim's AtomPub authority, because the authentication does not enforce nonce uniqueness or timestamp freshness. Only installations that enable the non-default AtomPub API with WSSE authentication and plaintext-compatible password storage are affected. Users are recommended to upgrade to Apache Roller 6.1.6 or later, which removes WSSE as an AtomPub authentication method; existing installations configured for WSSE fail closed until an administrator explicitly selects a supported authentication method.
