What is PgBouncer?

PgBouncer patches a SCRAM flaw that let a known user log in as an admin

PgBouncer's 1.26 line pairs features with a heavy security load. 1.26.0 tracks search_path and default_transaction_read_only by default, so one client's SET no longer leaks to others in transaction pooling, adds pool_idle_timeout and per-user query_wait_timeout, and removes the old online-restart takeover in favour of rolling restarts. It also fixed three CVEs. Three weeks later, 1.26.1 fixed three more, including one where a user with a password in auth_file could log in as any other SCRAM user, admins included.

What is Slurm?

Slurm's 26.05 line settles into routine fixes after September's seven-CVE release.

Slurm maintains three branches (25.05, 25.11, 26.05). On September 2 it shipped coordinated security releases on all three fixing seven CVEs, including an operator-to-administrator privilege escalation and SQL injection via cluster names. 26.05.5 on October 13 returned to ordinary fixes: qstat -f output, a slurmd double free and powered-down nodes placed incorrectly. 26.05.3 in August added external nodes in heterogeneous jobs.

PgBouncer patches a SCRAM flaw that let a known user log in as an admin

◆ Current state

PgBouncer's 1.26 line pairs features with a heavy security load. 1.26.0 tracks search_path and default_transaction_read_only by default, so one client's SET no longer leaks to others in transaction pooling, adds pool_idle_timeout and per-user query_wait_timeout, and removes the old online-restart takeover in favour of rolling restarts. It also fixed three CVEs. Three weeks later, 1.26.1 fixed three more, including one where a user with a password in auth_file could log in as any other SCRAM user, admins included.

◆ Where it's heading

Since 1.25.1 every release has carried CVE fixes in the authentication and packet-handling paths, and 1.26.1 found a second instance of a bug class fixed weeks earlier. The project is auditing its pre-auth surface in public, while 1.26.0 shows it still cleaning up long-standing pooling surprises.

◆ Prediction

More security point releases are likely while the auth and buffer code is under review; the entries give no sign of the next feature release.

2.5

Slurm's 26.05 line settles into routine fixes after September's seven-CVE release.

◆ Current state

Slurm maintains three branches (25.05, 25.11, 26.05). On September 2 it shipped coordinated security releases on all three fixing seven CVEs, including an operator-to-administrator privilege escalation and SQL injection via cluster names. 26.05.5 on October 13 returned to ordinary fixes: qstat -f output, a slurmd double free and powered-down nodes placed incorrectly. 26.05.3 in August added external nodes in heterogeneous jobs.

◆ Where it's heading

The 26.05 line, which introduced SLUID identity and an in-tree TLS path in May, is past its security scramble and into routine point releases. Older branches get backports only when a security fix requires it.

◆ Prediction

Expect 26.05.6 on a similar monthly pace with reliability fixes; another coordinated security release would again cover all three branches.
