The Apache Software Foundation shipped fixes for eight vulnerabilities across Apache Syncope, Apache Fineract and Apache Arrow Rust. The most severe, CVE-2026-64618, scores CVSS 9.8 and lets remote attackers run SQL injection without logging in. Maintainers report no exploitation in the wild and no public proof-of-concept code.
CVE-2026-64618 Leads Apache’s Batch; Fineract Gets Two Blind SQLi Fixes
CVE-2026-64618 is the top-rated issue in the batch, allowing remote, unauthenticated SQL injection. Apache Fineract, an open-source core banking platform, is affected in versions up to 1.15.0.
Fineract also received fixes for two critical time-based blind SQL injection bugs. In those, regex-based input validation can be bypassed by any authenticated user who has read access to centers or the targeted datatable. Banks that run Fineract face data theft and tampering if the flaws go unpatched.
Users are advised to upgrade to Fineract 1.16.1 to fix the blind SQL injection bugs.
Apache Syncope: Groovy Sandbox Bypass and Stacked Queries
Apache Syncope, an identity management system, received fixes for several flaws. One is a Groovy sandbox bypass in which a malicious Groovy class runs on a separate Thread, escaping the restrictions meant to contain scripts. Another, CVE-2026-114364, allows stacked SQL injection queries. The batch also covers unauthorized realm tree moves and process execution flaws.
Affected Syncope versions are 3.0.0-M0 through 3.0.16, 4.0.0-M0 through 4.0.8 and 4.1.0-M0 through 4.1.3. Users should upgrade to Syncope 4.0.9 or 4.1.4.
Why Syncope Identity Flaws Matter for Access Control
Identity management deployments hold account data and authorization rules for other systems, so a flaw that lets an attacker run unauthorized processes or move objects within the realm tree can alter who has access to what.
Apache Arrow Rust: Out-of-Bounds Read in CVE-2026-111959
Apache Arrow Rust is affected by CVE-2026-111959, an out-of-bounds read caused by improper validation of RunEndEncoded arrays that can leak memory. The affected range is versions 33.0.0 to 60.0.0 of the arrow crate, and the fix is in 60.1.0.
Arrow underpins many data pipelines, and a memory-disclosure flaw there can expose data held by the process that parses untrusted arrays. The issue is lower in severity than the SQL injection bugs, but it affects a library that applications embed widely.
Fineract, Syncope and Arrow Share an Input Validation Theme
The disclosures cover three unrelated projects, each with its own users and release process, but they share a theme: input validation that failed to hold up. In Fineract, regex checks could be bypassed. In Syncope, a sandbox did not contain scripts. In Arrow, array contents were not validated before reading.
Banks, identity platforms and data pipelines are all systems that hold information attackers value, and the absence of reported exploitation gives administrators a window before public technical detail circulates. The advisories name fixed releases for each product, so the upgrade path is clear: Fineract 1.16.1, Syncope 4.0.9 or 4.1.4, and the arrow crate 60.1.0.
Maintainers have not said who reported the flaws or whether any were found internally. With eight separate issues released in one day, organizations running more than one of these products will need to coordinate upgrades across teams that may not normally work together, particularly where Fineract and Syncope sit in the same financial-services stack.
No Exploitation or Public PoC for Any of the Eight Apache Flaws
Maintainers report no exploitation in the wild and no public proof-of-concept exploit for any of the eight flaws. The advisories were published together with fixed releases on the same day, so the details of each bug and its patch became available at once. That simultaneity gives attackers the same starting point as defenders, which is why the lack of public exploit code is a short-lived advantage.
