AliasVault is a privacy-first password manager with built-in email aliasing. Prior to 0.30.3, the AliasVault server API favicon extractor validates a user-supplied hostname with a first DNS lookup but allows the HTTP client to perform a second DNS lookup when connecting. An authenticated low-privileged user operating an attacker-controlled authoritative DNS server can return a public address during validation and a private address during connection, causing a publicly reachable self-hosted server to issue HTTP or HTTPS requests to internal hosts. A valid image response is returned in Base64 form, while other responses can expose limited timing and error information for internal-network reconnaissance. Exploitation requires a publicly reachable self-hosted instance with public registration enabled, an authenticated AliasVault account, an attacker-controlled authoritative DNS server, and a resolver that permits rebinding; default checks limit requests to ports 80 and 443. The browser extensions, web application, and mobile applications are not affected. This issue is fixed in version 0.30.3.

AliasVault is a privacy-first password manager with built-in email aliasing. Prior to 0.29.4, the AliasVault browser extension passkey provider does not bind passkey requests to the actual webpage origin or verify that the requested relying-party identifier matches the current website. A malicious website can provide forged origin and relying-party values and, if a victim with a matching stored passkey approves the AliasVault passkey prompt, obtain a valid assertion for a different website. Exploitation requires the extension to be installed, unlocked, and configured as a passkey provider, requires a stored passkey for the impersonated site, and cannot occur silently because the victim must approve the prompt. The server, web application, and mobile applications are not affected. This issue is fixed in version 0.29.4.

AliasVault is a privacy-first password manager with built-in email aliasing. A stored cross-site scripting (XSS) vulnerability was identified in the email rendering feature of AliasVault Web Client versions 0.25.3 and lower. When viewing received emails on an alias, the HTML content is rendered in an iframe using srcdoc, which does not provide origin isolation. An attacker can send a crafted email containing malicious JavaScript to any AliasVault email alias. When the victim views the email in the web client, the script executes in the same origin as the application. No sanitization or sandboxing was applied to email HTML content before rendering. This vulnerability is fixed in 0.26.0.[

Feb 23, 2026A vulnerability was identified in AliasVault App up to 0.25.3 on Android/iOS.CVE-2026-2974 · Other software · Aliasvault · reported by VulDBLow 1.1
A vulnerability was identified in AliasVault App up to 0.25.3 on Android/iOS. This vulnerability affects unknown code of the file shared_prefs/aliasvault.xml of the component Backup Handler. The manipulation of the argument accessToken/refreshToken/metadata/key_derivation_params/auth_methods leads to exposure of backup file to an unauthorized control sphere. An attack has to be approached locally. The attack is considered to have high complexity. It is stated that the exploitability is difficult. The exploit is publicly available and might be used. Upgrading to version 0.26.0 is able to resolve this issue. The identifier of the patch is 873ecc03f92238e162f98a068ad56069a922b4f6/0bd662320174d8265dfe3b05a04bc13efc960532. It is recommended to upgrade the affected component. The creator of the software explains: "Because of AliasVault's zero-knowledge encryption design, the tokens stored in aliasvault.xml are API session tokens that cannot decrypt the vault on their own: the master password is required for that. So while this isn't a direct vault compromise risk, there's no reason to include them in backups either."

AliasVault is a privacy-first password manager with built-in email aliasing. AliasVault Android versions 0.24.0 through 0.25.2 contained an issue in how passkey requests from Android apps were validated. Under certain local conditions, a malicious app could attempt to obtain a passkey response for a site it was not authorized to access. The issue involved incomplete validation of calling app identity, origin, and RP ID in the Android credential provider. This issue was fixed in AliasVault Android 0.25.3.

Sep 19, 2025AliasVault is a privacy-first password manager with built-in email aliasing.CVE-2025-59344 · Other software · aliasvault · reported by GitHubHigh 7.7
AliasVault is a privacy-first password manager with built-in email aliasing. A server-side request forgery (SSRF) vulnerability exists in the favicon extraction feature of AliasVault API versions 0.23.0 and lower. The extractor fetches a user-supplied URL, parses the returned HTML, and follows <link rel="icon" href="…">. Although the initial URL is validated to allow only HTTP/HTTPS with default ports, the extractor automatically follows redirects and does not block requests to loopback or internal IP ranges. An authenticated, low-privileged user can exploit this behavior to coerce the backend into making HTTP(S) requests to arbitrary internal hosts and non-default ports. If the target host serves a favicon or any other valid image, the response is returned to the attacker in Base64 form. Even when no data is returned, timing and error behavior can be abused to map internal services. This vulnerability only affects self-hosted AliasVault instances that are reachable from the public internet with public user registration enabled. Private/internal deployments without public sign-ups are not directly exploitable. This issue has been fixed in AliasVault release 0.23.1.

Where this comes from: the exploited list is CISA’s Known Exploited Vulnerabilities catalog. Everything else is the whole National Vulnerability Database, where each record is published by the team that found the bug (Wordfence, Patchstack, WPScan, the vendors themselves and others); we show who. Exploit odds are FIRST’s EPSS, updated daily. Titles and categories are ours, so check the linked record before acting on a detail. For a write-up of the big ones, see our advisories. Every vendor, and every WordPress plugin and theme with a recorded flaw, also has its own page. All of it is free to reuse as JSON, CSV or RSS.
