CVE-2026-74868: Technical Details & Mitigation

What is CVE-2026-74868 and which software is affected?

CVE-2026-74868 is a high-severity vulnerability in SiYuan Note (all versions before v3.7.4) that allows unauthenticated brute-force authentication bypass via the Publish Service. The flaw is due to missing rate limiting, lockout, or backoff mechanisms in the Basic Auth implementation, enabling attackers to guess publish-viewer account credentials without restriction. The vulnerability affects the SiYuan package github.com/siyuan-note/siyuan/kernel and is fixed in version 3.7.4 and later.
Note: This CVE impacts SiYuan Note, not the IONIX platform itself.

How can organizations mitigate CVE-2026-74868?

To mitigate CVE-2026-74868, organizations should immediately upgrade SiYuan Note to version 3.7.4 or later, which addresses the missing throttling in the Publish Service authentication path. If immediate patching is not possible, restrict network access to the Publish Service port (default 6808) to trusted IP ranges or place it behind a reverse proxy or WAF that enforces rate limiting and account lockout. Additionally, configure strong, high-entropy publish-viewer passwords to increase resistance to brute-force attacks.
Note: These mitigation steps apply to SiYuan Note deployments, not to IONIX users directly.

How does IONIX detect assets potentially exposed to CVE-2026-74868?

IONIX identifies potentially exposed assets by matching signals collected during its external attack surface discovery process.

CVE-2026-74868 – Unauthenticated Brute-Force Authentication Bypass – SiYuan Note before v3.7.4

Be the first to know when new zero-days emerge:

Summary

CVE-2026-74868 is an improper restriction of excessive authentication attempts (CWE-307) affecting SiYuan Note, an open-source personal knowledge management application. The flaw lies in the Basic Auth implementation of SiYuan’s Publish Service, which lacks any rate limiting, lockout, or backoff, allowing unauthenticated remote attackers to brute-force named publish-viewer account credentials. The issue carries a HIGH severity rating and affects all versions prior to 3.7.4.

Technical details

  • Root cause: PublishServiceTransport.RoundTrip() in kernel/server/proxy/publish.go validates Basic Auth credentials for the Publish Service without any per-account failed-attempt counter, lockout, or backoff mechanism.
  • The Publish Service runs on a separate listener from the main kernel API (default TCP port 6808) and is unauthenticated-by-default at the network layer, exposing it directly to the internet in typical deployments.
  • Named "publish-viewer" accounts (Conf.Publish.Auth.Accounts) are gated only by Basic Auth credentials chosen by the operator, with no enforced minimum length or complexity.
  • Attack vector: network, no privileges and no user interaction required — an attacker can submit unlimited password guesses against known or guessed account names.
  • Impact: successful credential guessing grants unauthorized read access to published notes and notebooks (confidentiality impact only; no integrity or availability impact per the CVSS vector).

Affected software

  • SiYuan (b3log/siyuan-note), package github.com/siyuan-note/siyuan/kernel — all versions before 3.7.4
  • Fixed in version 3.7.4 and later

Severity

  • CVSS v3.1 Base Score: 7.5 (HIGH) — CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N
  • CVSS v4.0 Base Score: 8.7 (HIGH) — CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N

Mitigation and recommended actions

  • Immediate: upgrade SiYuan to version 3.7.4 or later, which addresses the missing throttling in the Publish Service authentication path.
  • If immediate patching is not possible: restrict network access to the Publish Service port (default 6808) to trusted IP ranges or place it behind a reverse proxy/WAF that enforces rate limiting and account lockout; ensure strong, high-entropy publish-viewer passwords are configured to raise the cost of brute-force attempts.

How IONIX identifies potentially affected assets

IONIX matches the following signals against data already collected when it crawled the asset; identifying the technology sends no request beyond that crawl.

  • Page title: Access Authorization - SiYuan, 思源笔记
  • Raw response body: exitSiYuan, b3log.org/siyuan

How IONIX’s External Exposure Management Platform Detects and Validates
Zero-Days to Shrink MTTR

1

Map your entire attack surface (continously)

IONIX uses multi-factor discovery methods, including DNS analysis, certificate mapping, metadata inspection, and more, to automatically map every internet-facing asset across your environment. This includes cloud instances, third-party platforms, shadow IT, and even forgotten infrastructure that traditional tools miss.

2

Monitor for new CVEs

Dozens of threat intel feeds using agentic technology are continuously analyzed to detect the appearance of proof-of-concept code, exploit kits, and indicators of active targeting. IONIX goes further by applying AI to proactively evaluate whether emerging vulnerabilities are likely to be exploited, even before PoCs go public.

3

Identify Potential External Exposures

Not all CVEs matter. IONIX filters vulnerabilities by asking attacker-centric questions: Can it be reached from the internet? Does it require authentication? Is it being exploited in the wild? This dramatically reduces noise and focuses teams on threats that can actually be weaponized.

4

Create Safe, Scalable Exploit Validations

IONIX transforms real-world PoCs into safe, non-intrusive test payloads that can be run in production environments without disruption. These simulations are precisely targeted to the systems that are vulnerable, ensuring rapid validation without unnecessary load.

5

Execute Exploit Validations

By combining context about software stack, versioning, exposure status, and reachability, IONIX ensures that only the right payloads are executed against the right assets, maximizing efficiency and minimizing risk.

6

Drive Fast and Actionable Remediation

Results are routed through integrations with ticketing, SOAR, and SIEM tools. Issues are written in plain language, bundled into remediation clusters, and prioritized based on asset criticality, exploitability, and blast radius. This shortens mean time to remediation (MTTR) and empowers teams to act with confidence.
