Miniflux 2.3.0 through 2.3.3 contains a server-side request forgery vulnerability that allows authenticated users to reach internal addresses by setting a feed's proxy_url. Attackers can point proxy_url at loopback or internal hosts, bypassing FETCHER_ALLOW_PRIVATE_NETWORKS checks to probe internal ports and send proxy-style requests to internal services.

Aug 21, 2026Miniflux 2 is an open source feed reader.CVE-2026-55185 · Other software · miniflux · reported by GitHubMedium 5.1
Miniflux 2 is an open source feed reader. Prior to 2.3.1, IsRelativePath in internal/urllib/url.go accepts redirect targets containing backslashes because Go URL parsing treats them as path characters. Browser backslash normalization converts them to forward slashes. An unauthenticated attacker can provide such a redirect_url value to the login flow, bypass the relative-path and host checks, and redirect a victim to an attacker-controlled external site. This issue is fixed in version 2.3.1.

Jan 8, 2026Miniflux 2 is an open source feed reader.CVE-2026-21885 · Other software · miniflux · reported by GitHubMedium 6.5
Miniflux 2 is an open source feed reader. Prior to version 2.2.16, Miniflux's media proxy endpoint (`GET /proxy/{encodedDigest}/{encodedURL}`) can be abused to perform Server-Side Request Forgery (SSRF). An authenticated user can cause Miniflux to generate a signed proxy URL for attacker-chosen media URLs embedded in feed entry content, including internal addresses (e.g., localhost, private RFC1918 ranges, or link-local metadata endpoints). Requesting the resulting `/proxy/...` URL makes Miniflux fetch and return the internal response. Version 2.2.16 fixes the issue.

Dec 10, 2025Miniflux 2 is an open source feed reader.CVE-2025-67713 · Other software · miniflux · reported by GitHubMedium 5.3
Miniflux 2 is an open source feed reader. Versions 2.2.14 and below treat redirect_url as safe when url.Parse(...).IsAbs() is false, enabling phishing flows after login. Protocol-relative URLs like //ikotaslabs.com have an empty scheme and pass that check, allowing post-login redirects to attacker-controlled sites. This issue is fixed in version 2.2.15.

Apr 3, 2025Miniflux is a feed reader.CVE-2025-31483 · Other software · miniflux · reported by GitHubMedium 4.8
Miniflux is a feed reader. Due to a weak Content Security Policy on the /proxy/* route, an attacker can bypass the CSP of the media proxy and execute cross-site scripting when opening external images in a new tab/window. To mitigate the vulnerability, the CSP for the media proxy has been changed from default-src 'self' to default-src 'none'; form-action 'none'; sandbox;. This vulnerability is fixed in 2.2.7.

Mar 17, 2023Miniflux is a feed reader.CVE-2023-27592 · Other software · miniflux · reported by GitHubMedium 4.8
Miniflux is a feed reader. Since v2.0.25, Miniflux will automatically proxy images served over HTTP to prevent mixed content errors. When an outbound request made by the Go HTTP client fails, the `html.ServerError` is returned unescaped without the expected Content Security Policy header added to valid responses. By creating an RSS feed item with the inline description containing an `<img>` tag with a `srcset` attribute pointing to an invalid URL like `http:a<script>alert(1)</script>`, we can coerce the proxy handler into an error condition where the invalid URL is returned unescaped and in full. This results in JavaScript execution on the Miniflux instance as soon as the user is convinced (e.g. by a message in the alt text) to open the broken image. An attacker can execute arbitrary JavaScript in the context of a victim Miniflux user when they open a broken image in a crafted RSS feed. This can be used to perform actions on the Miniflux instance as that user and gain administrative access to the Miniflux instance if it is reachable and the victim is an administrator. A patch is available in version 2.0.43. As a workaround sisable image proxy; default value is `http-only`.

Mar 17, 2023Miniflux is a feed reader.CVE-2023-27591 · Other software · miniflux · reported by GitHubHigh 7.5
Miniflux is a feed reader. Prior to version 2.0.43, an unauthenticated user can retrieve Prometheus metrics from a publicly reachable Miniflux instance where the `METRICS_COLLECTOR` configuration option is enabled and `METRICS_ALLOWED_NETWORKS` is set to `127.0.0.1/8` (the default). A patch is available in Miniflux 2.0.43. As a workaround, set `METRICS_COLLECTOR` to `false` (default) or run Miniflux behind a trusted reverse-proxy.

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.
