Use-After-Free in BTREE Index Traversal via Stale key_version in heap_update() in MariaDB Server

🔹 Severity: No Rating
🔹 Weakness: Use After Free
🔹 Reported To: MariaDB
🔹 Reported By: lukas_kupczyk
🔹 State: 🟢 Resolved
🔹 Disclosed: September 14, 2026, 4:05pm (UTC)
🐞 Source: HackerOne

A use-after-free vulnerability was discovered in the MEMORY (HEAP) storage engine of MariaDB Server. The vulnerability was caused by incorrect handling of the `key_changed` variable in the `heap_update()` function, which could lead to stale pointers being dereferenced during BTREE index traversal. While the vulnerability could be triggered by an authenticated user with standard database privileges, no further…

Incomplete fix for CVE-2022-23915: Mercurial argument injection in HgRepository.get_file() leads to command execution

🔹 Severity: High

🔹 State: 🟢 Resolved
🔹 Disclosed: September 15, 2026, 8:36am (UTC)
🐞 Source: HackerOne

A vulnerability was discovered in Weblate, a web-based translation tool. The vulnerability was caused by an incomplete fix for a previous issue (CVE-2022-23915). Weblate passed repository-controlled filenames to Mercurial without properly escaping them, allowing filenames beginning with "-" to be interpreted as command-line options. This could be abused by an authenticated user with project-scoped component-edit…

Stack Buffer Overflow via Crafted keyseg->start/ keyseg->length in .MYI File (MariaDB MyISAM)

🔹 Severity: No Rating
🔹 Weakness: Classic Buffer Overflow
🔹 Reported To: MariaDB
🔹 Reported By: lukas_kupczyk
🔹 State: 🟢 Resolved
🔹 Disclosed: September 15, 2026, 9:37am (UTC)
🐞 Source: HackerOne

A stack buffer overflow vulnerability was discovered in the MyISAM storage engine of MariaDB. The vulnerability was caused by lack of validation of the "keyseg->start" and "keyseg->length" fields read from the .MYI file. This allowed an attacker to write data beyond the bounds of a fixed-size stack buffer, leading to a denial of service condition when a SQL query touched the affected table's key.

🔹 State: 🟢 Resolved
🔹 Disclosed: September 15, 2026, 9:38am (UTC)
🐞 Source: HackerOne

A vulnerability was discovered in the `JSON_ARRAYAGG` aggregate function of MariaDB Server. The vulnerability was caused by an integer underflow in the `cut_max_length` function, which could allow an authenticated user to read arbitrary heap memory from the server process. The vulnerability was introduced in commit 6c573a9146caa76807db1190e0747f5befb5b170 (2020-06-15) and affected versions of MariaDB Server prior…

Stack Buffer-Overflow in MariaDB Charset_collation_map_st::insert_or_replace()

🔹 Severity: No Rating
🔹 Weakness: Stack Overflow
🔹 Reported To: MariaDB
🔹 Reported By: lukas_kupczyk
🔹 State: 🟢 Resolved
🔹 Disclosed: September 15, 2026, 9:39am (UTC)
🐞 Source: HackerOne

A stack-based buffer overflow was discovered in the MariaDB Server's `Charset_collation_map_st::insert_or_replace()` function. The function copied user-supplied charset and collation identifiers into fixed-size stack buffers using `strmake()` with the attacker-controlled token length as the size bound instead of the destination buffer size. This could have been leveraged by an authenticated user to crash the entire…
